BUGS
	o ^D (EOF) on stdin causes input routines to endlessly loop.
	o When the programme asks "What is the probability of getting
	  the improbability?" the answer is assumed to contain a
	  decimal point.  If none is entered, a signal SEGV occurs.
	
FIXES
	o A routine was added to parser.c named trapEOF and the eofgets()
	  macro facilitates this call.  ^D now terminates the programme
	  with exit code 1.
	o The input to the question now accepts forms of 50, 50.7, 0.50
	  and 1/2, all returning a value equivalent to 50%.  Other input
	  (1/,fifty percent) will simply be interpreted as 0.

AESTHETIC CHANGES
	o A -f option was allowed.  This causes the programme to start
	  in the researcher's office.  The title and instructions are skipped.
	o The prompt at the end of the title screen lets you skip the 
	  instructions.
	o srand() is now randomized by the system clock.  It had been 
	  randomized by the values returned from get_enter() at the
	  first two screens, but this usually resulted in sum being
	  always set to a value of 86 as most people don't type anything
	  at a prompt that says to just press <enter>.
	o The code now passes the lint test.  It barfed in a big way
	  with the original code as numerous return codes were not
	  checked and some return values were inconsistent. The
	  latter was caused by the absence of string.h; to keep
	  portability, I included extern definitions to the
	  common string functions used in the programme.  I don't
	  know whether it will compile with Datalight (?) C
	  as I don't have access to that compiler.  All casting
	  to (void) will also have to be removed on compilers
	  without void.
	o fgets replaced all gets calls because gets is inherently
	  evil.
	o The printing of the title screen when exiting the programme
	  has been removed.  It just isn't in the spirit of UNIX.  |:-)
