Explicit-ness

[Allen Winter]

Howdy,

I'm working on a need Krazy plugin that checks for constructors that should be
declared explicit according to the following rules:

 - constructor must be public
 - constructor must have exactly 1 required argument 
 - constructor may have 1 or more optional arguments
 - a class may have more than constructor declared 'explicit'
 - copy constructors should not be declared 'explicit'
 - templates ignored

Any other requirements I should add?

I hope to install this plugin into Krazy on the EBN for tomorrow's run.

Here's sample output from kdelibs/kdecore
