char** findFirstCaptures	(	const char *	pattern,
		const char *	s
	)

This file defines APIs for regular expression calls.

Current implementation is c++11 regex library that should be well supported across platform.

Author:

Shaoqin(Bobby) Lu find captures in the first matched substring using the provided regular expression pattern on the target string.

TODO this feels a little not as flexible. Maybe make a function that takes int n to find first n matches and all captures

example: pattern="abcd([0-9]+)" s="abcd1234abcd5678" return ["1234", NULL]

Parameters:

	pattern	the regular expression pattern
	s	the target string

Returns:

An array of string representing the captured substrings terminated with a NULL, caller is responsible to free the consumed memory
