This is a simple class that used to do more initialization for crucial but has now been made much simpler.
It only adds an optional GUI skin.
Pending deprecation.
initSpecs will be moved somewhere
Adds a GUI skin named \crucial.
This skin is slightly cleaner and more basic than the default. Put GUI.setSkin(\crucial) in your startup if you wish to use it.
This defines a bunch of Specs which I find are useful. Nothing depends on these.
