	ABSTRACT	: The deafult strcmp() merely returns info 
			  about which string is lexographically 
			  greater, but e_strcmp() returns the 
			  difference between the words where the 
			  first char difference between the strings.

	Description	: If the returned integer is positive then
			    *p string is lexographically greater than *q.
			  If the returned integer is negative then
			    *p string is lexographically lesser than *q.
			  If the returned integer is 0 *p is identical
			    to *q
			  If the returned integer is greater than 27
			    then the *q string is a substrng of *p
			  If the returned integer is less than -27 then
			    the *p string is a substring  of *q
