These simple C tests are organized based upon their main principle, with the
test name reflecting its type:
  -- Basic        (b)
  -- Arithmetic   (a)
  -- aGgregate    (g)
  -- Routines     (r)
  -- String       (s)
  -- Conversion   (c)
  -- Pointer      (p)
  -- control Flow (f)
  -- Misc         (m)

NOTE: In no way is this simple set of C correctness tests meant to be 
comprehensive or complete. It is just a sample that can freely be altered
or extended. In addition, the makefile is is quite naive; much finer
control can be achieved by providing build rules for each test or generating
separate makefiles for each test. In its current state, using the command
`make clean ; make ; make clean` will build and run all the tests as well
as leave the directory clean at the finish.
