Rule author

I am the original author. All these rules come from this repo:

https://github.com/pfultz2/cppcheck-rules

Except the rules are out of date. These rules have been updated to make them more robust. For example the `EmptyIfStatement` rule checks for nested parenthesis: `if (\([^()]*(?-1)*[^()]*\)) { }` but the one in the repo is much older and does not.

There are also additional rules available.
