cs_destroy - clean up and dealloc a parse tree
#include <cs/cs.h>
void cs_destroy (CSPARSE **parse);
parse - a pointer to a parse structure.
cs_destroy will clean up all the memory associated with a CSPARSE structure,
including strings passed to cs_parse_string. This does not clean up any memory
allocated by your own CSOUTFUNC or the HDF data structure passed to cs_init.
It is safe to call this with a NULL pointer, and it will leave parse NULL as
well (ie, it can be called more than once on the same var)
