Added match() function based on boolean predicate func

Addressing the following issue - #167
Added this simple implementation of the match() method based on a boolean predicate func() parameter.

This looks good to me, but I would name this Matches, not Match. That reads a bit better when used in an if clause, IMO. I'd also note that the stdlib often uses names like MatchesFunc for funcs that take other funcs as an argument, for example the various functions in sort and slices.

Agreed, changed this.
