1. Adjustable support apparatus for a rifle in a shooting position in a window of a wall, comprising: an elongated member having a forward end including a first pivot part and a rearward end;a forward support assembly pivotably attached to the forward end of the elongated member; anda rearward support assembly, including a rifle stock support and a sliding adjustment collar joined by a turnbuckle coupling therebetween, slidingly installed on the rearward end of the elongated member; whereinthe forward support assembly includes an adjustable transverse clamp mechanism for supporting the rifle on a sill member of a window, a rifle barrel support, and a transverse adjustment brace for elevation and azimuth of the longitudinal axis of the rifle; andthe rearward support assembly includes the rifle stock support for resisting recoil and adjustments for the length and height of the rifle. 2. The apparatus of claim 1, wherein: the longitudinal axes of the elongated member and the rifle are disposed in a substantially horizontal orientation. 3. The apparatus of claim 1, wherein the elongated member comprises: a first rigid member having a rectangular or triangular cross section, a length similar to a substantial portion of the length of the rifle to be supported by the apparatus, and a first pivot part at the forward end of the first rigid member. 4. The apparatus of claim 1, wherein the forward assembly further comprises: a second rigid member having a second pivot part extending rearward from the lower end thereof and the adjustable transverse clamp mechanism attached transverse to its upper end for supporting the apparatus securely on a window sill;the transverse adjustment brace adjustably connected to the second rigid member above the lower end thereof for adjusting the elevation angle of the rifle; andthe second pivot part configured to cooperate with the first pivot part of the elongated member in pivotably supporting the forward end to enable adjustment of the azimuth angle of the elongated member. 5. The apparatus of claim 4, wherein the second pivot part comprises: first and second parallel arms extending rearward from the lower end of the second rigid member. 6. The apparatus of claim 1, wherein the adjustable transverse clamp mechanism comprises: a vise formed by a fixed jaw at the upper end of the second rigid member and a movable transverse jaw slidingly disposed along a horizontal rail extending forward from the fixed jaw; whereinthe movable transverse jaw and a downward extension thereof is caused to move along the horizontal rail by a first adjusting screw connecting the fixed jaw to matching internal threads in the movable jaw, to enable clamping a window sill in the vise. 7. The apparatus of claim 6, wherein: the first adjusting screw includes a first adjusting knob. 8. The apparatus of claim 4, wherein the adjustable transverse clamping mechanism comprises: a fixed jaw attached to the upper end of the second rigid member and a movable transverse jaw slidingly disposed along a horizontal rail extending from the fixed jaw thereby forming a vise;wherein a screw disposed parallel to the rail and though the fixed jaw is threadably engaged with the movable transverse jaw to enable tightening or loosening the vise by turning a knob attached to the screw. 9. The apparatus of claim 1, wherein the rifle barrel support comprises: a U-shaped yoke extending upward from a swiveling post disposed on top of the adjustable clamp mechanism. 10. The apparatus of claim 4, wherein the adjustment for elevation comprises: a transverse adjustment brace disposed across the forward side of the second rigid member and below the upper end thereof, the transverse adjustment brace movable forward or rearward to adjust the distance between the lower end of the second rigid member and the wall below the window sill, thereby varying the angle of elevation of the longitudinal axis of the elongated member. 11. The apparatus of claim 10, wherein: the transverse adjustment brace is coupled to the second rigid bar by a sliding bracket attached to the transverse adjustment brace and adjustable by an adjusting screw turned by a second adjusting knob supported by the sliding bracket. 12. The apparatus of claim 1, wherein the rearward support assembly comprises: the sliding adjustment collar with a set screw, the collar configured for sliding along the elongated member for adjusting the position of the rearward assembly along the elongated member, the collar further having a first threaded rod extending upward from the collar;the rifle stock support for retaining the rifle stock and limiting side-to-side and rearward motion thereof, and a second threaded rod of opposite thread from the first threaded rod extending downward from the stock saddle; andthe turnbuckle coupling for joining distal ends of the first and second threaded rods for adjusting the distance between the collar and stock saddle, such that the stock saddle is positioned above the collar and elongated member, to adjust the height of the rifle stock relative to the elongated member. 13. The apparatus of claim 12, wherein: the first threaded rod comprises a bolt having a left hand thread pitch; andthe second threaded rod comprises a bolt having a right hand thread pitch. 14. The apparatus of claim 12, wherein the set screw comprises: a third knob attached to the set screw for turning the set screw to secure or loosen the collar along the elongated member. 15. The apparatus of claim 1, wherein the elongated member comprises: a first rigid member having a length similar to a substantial portion of the length of the rifle to be supported by the apparatus, and a first pivot part at the forward end of the first rigid member. 16. The apparatus of claim 10, wherein the stock support comprises: a lining to cushion the rifle stock; anda strap for securing the rifle stock within the stock saddle. 17. The apparatus of claim 16, wherein the strap includes: first and second parts of a hook and loop fastener. 18. The apparatus of claim 9, wherein the U-shaped yoke includes: a cladding of cushion material. 19. The apparatus of claim 4, wherein: the first and second pivot parts cooperate to permit horizontal movement and orientation of the elongated member relative to the second rigid member. 20. The apparatus of claim 19, wherein: the first and second pivot parts are pivotably joined by a pin oriented substantially parallel to the second rigid bar. 21. The apparatus of claim 20, wherein: the pin comprises a bolt secured through respective holes in the first and second arms aligned with a corresponding hole in the forward end of the elongated member. 22. The apparatus of claim 1, wherein the apparatus may be disassembled for transport and storage.
