* Copy sjava.lex, sjava.grm, and semantic.c from the previous project
  into this directory

* Modify AATBuildTree.c to build AATs

* Modify testBuildTree.c so that it tests a wider range of
  calls to AATBuildTree functions

* Modify semantic.c to return an AAT

* Compile and test with

  %  make
  %  ./testBT               (to test AATBuildTree functions)
  %  ./a.out <filename>     (to test AAT generator)

Included files:

testBuildTree.c    Program to test AATBuildTree (includes main())
                     (needs to be modified to expand test cases!)
assemblytest.c     Program to to test assembly generation (includes main())

semantic.h           an AAT (DONT use this file:  modify your own semantic.c)
