nugrant 1.2.0

Nugrant is a library to easily handle parameters that need to be injected into an application via different sources (system, user, project, defaults). Nugrant can also be directly used as a Vagrant plugin. By activating this gem with Vagrant, it will be possible to define user specific parameters that will be injected directly into the Vagrantfile. This is useful if you need to share a Vagrantfile to multiple developers but would like to customize some parameters for each user differently.
