split { onto new lines.

used fputs instead of fprintf for efficiency
added if( print ) checks.
and print and verbose as public variables (set by main)

and used instead of some printfs.
added print_shape to simplify things a teensy weensy bit.

then added the indentation system,
ie. numtabs, indent(), outdent(), line().
seems to work so far.
still empty unions generated though.

not used to alter code gen yet.

(the .c generated prior to optimization contains
a zero-sized union though, which is wrong)

also: TRUE and FALSE were wrong way round (oops)
and I have removed ABORT.. explicit error mesgs on stderr now.

renamed some procedures.
some silly little { onto new lines.
important change: added the print functions and prototypes.

added verbose flag.

parameters.

parsing done, just needs decs updating now..
