StringEx v0.2.1

Now StringEx can treat '(' and ')' as plain text when has backslash before. But still does not work with regex which contains sub regex constructs.

Example:
   + If regex = "\\(aaa", getAllRegexConstructs() will return an empty array.
   + If regex = "\\(aaa\\) bbb (\\d)", getAllRegexConstructs() will return an array which contains only "\\d".
