The invention claimed is: 1. A safety latch apparatus for retaining a movable member of an opening assembly in a closed or substantially closed position relative to a fixed position member of an opening assembly, said opening assembly having a fixed position member and a movable member, said safety latch apparatus comprising: a receiving assembly having a base portion for mounting to said fixed position member or said movable member and a single receiving element protruding from said base portion; and a latching assembly engageable with said receiving element, said latching assembly comprising: an arm comprised of compliant material and having a separate hook element coupled at the end thereof, said biased compliant arm biasing said hook element towards said receiving element, wherein said receiving element engages said hook element; a latching assembly mounting mechanism for mounting said biased compliant arm to said fixed position member or movable member such that the receiving assembly and latching assembly are mounted on cooperating fixed position member and movable member, said latching assembly mounting mechanism further comprising an arm retaining plate coupled to said fixed position member or said movable member and also coupled to said biased compliant arm, and said latching assembly mounting mechanism comprising an arm cover plate removably coupled to said biased compliant arm, wherein the arm cover plate has a contacting surface with the biased compliant arm; and a means for disassembling said latching assembly mounting mechanism while leaving the arm retaining plate coupled to said fixed position member or said movable member and removing said arm cover plate and said biased compliant arm in order to allow said opening assembly to freely open. 2. The apparatus of claim 1, wherein the biased compliant arm is curved to predispose said hook catching element towards said receiving element to facilitate engagement with said receiving element. 3. The apparatus of claim 1, wherein said catch element and said receiving element engage at a single point. 4. The apparatus of claim 1, wherein the arm cover plate further comprises removable sections wherein removal of removable sections facilitate proper fit on a door frame. 5. A safety latch apparatus for retaining a swinging door in a closed or substantially closed position relative to a door frame in a door unit, said door unit having a first fixed member and a second movable member, said safety latch comprising: a receiving assembly having a base portion for mounting to said first fixed position member or said second movable member and a single receiving element protruding from said base portion; and a latching assembly engageable with said receiving element, said latching assembly comprising: a curved compliant arm wherein the curvature of the arm is substantially the same or greater than a curvature of the arc of the swinging door; a separate catch element coupled at the end of the compliant arm, wherein said curved compliant arm biases said catch element towards said receiving element to facilitate engagement with said receiving element upon movement of said catch element and said receiving element towards each other; a latching assembly mounting mechanism for mounting said curved compliant arm to said first fixed position member or said second movable member such that the receiving assembly and latching assembly are mounted on cooperating first fixed position and second movable members, said latching assembly mounting mechanism further comprising an arm retaining plate coupled to said fixed position member or said movable member and also coupled to said curved compliant arm, wherein the arm retaining plate further comprises a channel and at least one alignment head located in said channel, and wherein said curved compliant arm is placed in said channel and couples to said at least one alignment head, wherein said at least one alignment head prevents said curved compliant arm from rotating, said latching assembly mounting mechanism further comprising an arm cover plate removably coupled to said curved compliant arm, and wherein the arm cover plate has a contacting surface with said curved compliant arm; and a means for disassembling said latching assembly mounting mechanism while leaving the arm retaining plate coupled to said fixed position member or said movable member and removing said arm cover plate and said curved compliant arm in order to allow said swinging door to freely open. 6. The apparatus of claim 5, wherein the catch element of the latching assembly is slideable and lockable on the compliant arm. 7. The apparatus of claim 5, further comprising a finger protector. 8. The apparatus of claim 5, wherein the catch element comprises, a hook for engaging said receiving element at a single point when said receiving element and said catch element are moved toward each other. 9. The apparatus of claim 5, wherein the latching assembly base portion comprises a mounting mechanism, wherein the compliant arm may be removably coupled to the mounting mechanism. 10. The apparatus of claim 9, wherein the mounting mechanism is mounted, such that an engaged safety latch device transfers forces in shear to the door frame. 11. The apparatus of claim 5, wherein the catch element comprises a user interactive portion for deflecting the compliant arm away from the receiving element. 12. A safety latch apparatus for retaining a swinging door in a closed or substantially closed position relative to a door frame in a door unit, said door unit having a first fixed position member and a second movable member, said safety latch comprising: a receiving assembly having a base portion for mounting to said first fixed position member or said second movable member and a single receiving element protruding from said base portion; and a latching assembly engageable with said receiving element, said latching assembly comprising: a compliant arm having a separate catch element coupled at the end of the compliant arm, wherein said catch element and said receiving element engage each other at a single point when said swinging door is in a closed or substantially closed position; a latching assembly mounting mechanism for mounting said compliant arm to said first fixed position member or said second movable member such that the receiving assembly and latching assembly are mounted on cooperating first fixed position and second movable members, said latching assembly mounting mechanism further comprising an arm retaining plate coupled to said fixed position member or said movable member and also coupled to said compliant arm, said latching assembly mounting mechanism further comprising an arm cover plate removably coupled to said compliant arm, and wherein the arm cover plate has a contacting surface with said compliant arm; a means for disassembling said latching assembly mounting mechanism while leaving the arm retaining plate coupled to said fixed position member or said movable member and removing said arm cover plate and said compliant arm in order to allow said swinging door to freely open; and a means for reassembling said latching assembly mounting mechanism in order to once again restrict motion of the swinging door. 13. The apparatus of claim 12, wherein said latching assembly comprises a curved compliant arm such that a curvature of the arm is substantially the same or greater than a curvature of the arc of the swinging door. 14. The apparatus of claim 12, wherein the compliant arm is biased to predispose said catch element towards said receiving element to facilitate engagement with said receiving element. 15. The apparatus of claim 12, wherein the catch element of the latching assembly is slideable and lockable on the compliant arm. 16. The apparatus of claim 12, wherein the catch element of the latching assembly is removable from the compliant arm. 17. The apparatus of claim 12, wherein the catch element comprises a user interactive portion for deflecting the compliant arm away from said receiving element. 18. The apparatus of claim 12, wherein the latching assembly base portion comprises a mounting mechanism, wherein the compliant arm is removably coupled to the mounting mechanism. 19. The apparatus of claim 12, wherein the receiving element bends to fit swinging doors of different thicknesses. 20. The apparatus of claim 19, further comprising a finger protector.
