Derivative parser for regular expressions

[lawrancej]

Write a function that takes in a regular expression and a character, and produces a new regular expression, called the derivative, as described in http://matt.might.net/articles/parsing-with-derivatives/ and http://matt.might.net/papers/might2011derivatives.pdf. The function will use the visitor class (see examples/visitor-demo.c for an idea).

GObject *compilerkit_derivative_parser(GObject *regex, gunichar symbol)

Here's an example of this in Java.
