Thanks for the PR! Unfortunately, the build is now failing because Coveralls seems to require 5.5+ but the library supports 5.3+. If you can find a way to get the build to pass with 5.3+ (probably pin the Coveralls version), I can merge the request.

@archwisp We should use "satooshi/php-coveralls": "~1.0" since it supports PHP 5.3, not dev-master. Any reason to use dev-master?

I tried to use "satooshi/php-coveralls": "~1.0", but I got:

Why do we need "classmap": [""],?

@umpirsky Thanks for the PR! I opened the following PRs to fix the issues you found:

#19 - Remove classmap from Composer config
#20 - Pin satooshi/php-coveralls to PHP 5.3+ compatible version

Once those are merged we can rebase against master to see your PR's updated Travis runs.

@johnkary Wow, that was fast!

However, better ever then never. :)
