e850bff60f Hk cyclomatic complexity (#92) 
* Proof of concept for cyclomatic complexity

* Enable configurability of rule

* Use the same nodes to increment the complexity as rubocop

* Fix typo in test description

* Properly indent code and simplify macro

* Move metric into metrics

* Cover a violation supressed by increased threshold

* Extract visitor into its own file

* Document cyclomatic complexity rule and visitor

* Refactor specs to use a macro

* Indent code inside macro

* Replace array with tuple for string formatting.

`Tuple` is stack based, whereas `Array` is allocated on the heap increasing GC pressure.

* Fix formatting

* Enable cyclomatic complexity rule by default

Performance improvements (#15) 
* Performance improvements

Two main changes:

1. Cache parsed AST in a Source. So Parser will parse content only once.
2. Use one unified visitor with multiple callbacks instead of multiple
visitors to traverse AST.

This improves performance significantly, for example running it on
Crystal repository takes ~1 second, which 6 times faster than before.

* Change readme example
