varnam		-	vtypes.h	Contains pointer to scheme file, log file, and a varnam_internal instance
varnam_internal	-	vtypes.h	Lots of stuff. pointers to the sqlite database, string buffers, 
varray_t/varray	-	varray.h	Contains [void **memory],allocated and used memory, and an index
vpool_t/vpool_t	-	varray.h	Contains 2 varrays (*array,*free_pool)
token/vtoken	-	vtypes.h	contains pattern,tag,priority etc for each token. That is, stores a token and the associated information
strbuf		-	util.h		A string buffer. Basically contains a character array, and its length.
vcache_entry	-	vtypes.h	[guessing] An entry in the cache. 


FUNCTIONS

vst_tokenize	-	symbol-table.c	Deals with tokenization. Seems pretty important
varray_clear	-	varray.c	Clears the varray that is passed as an argument. Sets memory->* as NULL
strbuf_to_s	-	strbuf.c	Returns the string that is stored in strbuf. That is , return strbuf_element->buffer
read_all_tokens_and_add_to_array	-	symboltable.h


MACROS

READ_A_UTF8_CHAR	-	util.h	Receives a ustring,input_stirng and bytes_read. Copies input_string to ustring and increments bytes_read.
				Finally, ustring contains the unicode version of input_string and bytes_read contain its size.
