String comparison

Compares 2 strings. Output is identical to that of C string library.

Compares 2 strings, str1 and str2 and return -1 if str1 < str2, 0 if str1==str2 and 1 if str1 > str2. output is identical to that of C string library.
Same idea as files listed in acknowledgments. The difference is that this implementation is faster since it uses mex function.
Type mex strcmpC.c at the MATLAB prompt to generate the mex file. Then call strcmpC like any MATLAB function.
Example usage:
strcmpC('1234','2345535')
ans =
-1
Source code heavily references a mex example. See mxmalloc.c.
Type the following command in MATLAB prompt to see mxmalloc.c
