  Most of the grid classes can be customized with the exception of the helper clases

• What is the current behavior?
  Currently you cannot prefix these classes which creates conflicts with other packages.

• What is the expected behavior?
  Allow to have a scss variable you can set to prefix helper classes/

Ah yes, I can see how that would conflict with other libraries...
I like the idea of adding an scss variable to prefix the helper classes and will implement it ASAP.

[lucasgruwez]

Done! v1.3.6, use $helper-prefix to set the prefix for the helper classes, for example, if its set to "waffle-", the classes would be .waffle-center, .waffle-m-hide, etc...
