lib/simplecov.rb:60: warning: instance variable @track_files_glob not initialized

[fornellas]

Hello,

It seems Simplecov module expect some instance variables to be set up by SimpleCov::Configuration. Of course the default value nil works, however, we get warnings from Ruby VM. I believe this could be solved by improving SimpleCov::Configuration to either preset unset variables to nil, or, check them with Object#instance_variable_defined? before using.

If you think any of these is a good solution (or even suggest a better one), I can make the patch an pull request.

Sincerely,

I like initializing to nil. PR would be fantastic!
