1. A door barricade apparatus, said apparatus comprising: a base having a first end including a door engaging member extending vertically from the base, a mid-section of the base having a thickness dimension less than a spacing between a floor and a bottom edge of a door, and a unitary support member extending vertically from the base wherein said support member has a front plate and a back plate spaced apart from one another, said front plate of said unitary support member being spaced apart and opposing the door engaging member and said back plate of said unitary support member terminating at a second end of the base that opposes the first end of the base, and further wherein a top of the front plate is interconnected with a top of the back plate of the unitary support member via a top plate;a first fixed extension extending tangentially outward from the back plate of said unitary support member, said first extension adapted to engage a first side of a doorjamb and adjacent wall section;a second fixed extension extending tangentially outward from the back plate of said unitary support member and extending outwardly in a direction opposite the first extension and wherein said second extension is adapted to engage a second side of the door jamb and adjacent wall section that opposes the first side of the door jamb; anda pressing member coupled to the support member, said pressing member having a first end extending outward towards said door engaging member from the front plate of said support member and having a second end extending outward and away from the back plate of said support member, said pressing member being adaptable to apply a force to the door to thereby sandwich the door between the door engaging member and a portion of the first end of the pressing member. 2. The door barricade apparatus as recited in claim 1, wherein said pressing member includes a threaded rod rotatably coupled to said support member, further wherein said second end of said pressing member terminates in a knob. 3. The door barricade apparatus as recited in claim 2, wherein the first end of the pressing member further includes a pliant stop coupled to the first end of the pressing member. 4. The door barricade as recited in claim 1, further including felt on an inner surface of the door engaging member. 5. The door barricade apparatus as recited in claim 1, further including felt on an inner portion of the mid-section of the base. 6. The door barricade apparatus as recited in claim 1, further including felt on an underside of the base. 7. The door barricade apparatus as recited in claim 3, wherein said support member has a hollow section extending between the front plate and the back plate of the support member. 8. A method of barricading a classroom door from rotating out away from a classroom and to restrict entry into the classroom, said method including the steps of: positioning a door barricade apparatus in alignment with a door, a doorjamb, and an adjacent wall section, said door barricade apparatus including:a base having a first end including a door engaging member extending vertically from the base, a mid-section of the base having a thickness dimension less than a spacing between a floor and a bottom edge of a door, and a unitary support member extending vertically from the base wherein said support member has a front plate and a back plate spaced apart from one another, said front plate of said unitary support member being spaced apart and opposing the door engaging member and said back plate of said unitary support member terminating at a second end of the base that opposes the first end of the base, and further wherein a top of the front plate is interconnected with a top of the back plate of the unitary support member via a top plate;a first fixed extension extending tangentially outward from the back plate of said unitary support member, said first extension adapted to engage a first side of a doorjamb and adjacent wall section;a second fixed extension extending tangentially outward from the back plate of said unitary support member and extending outwardly in a direction opposite the first extension and wherein said second extension is adapted to engage a second side of the door jamb and adjacent wall section that opposes the first side of the door jamb; anda pressing member coupled to the support member, said pressing member having a first end extending outward towards said door engaging member from the front plate of said support member and having a second end extending outward and away from the back plate of said support member, said pressing member being adaptable to apply a force to the door to thereby sandwich the door between the door engaging member and a portion of the first end of the pressing member. 9. The method as recited in claim 8, wherein the first end of the pressing member further includes a pliant stop, and further including the step of engaging the pliant stop against the door. 10. The method as recited in claim 8, wherein the step of positioning the door barricade apparatus further includes aligning the first or second extension to overlap an adjacent portion of the door jamb and wall.
