Re: Create a new Complexity check

It is possible to persist information across calls. The instance of the
Check is created once and used.

If you extend AbstractComplexityCheck, you can override beginTree() and
endTree() to know when processing starts and finishes. You will need to copy
the implementation of visitTokenHook() to determine the complexity of each
method.

Probably need to add hooks to determine package names as well.
