Convert Component::get(set)StateVariable() to get(set)StateVariableValue() to reflect that StateVariable object is not returned and only the value.
Rename Component methods to reflect that the get/set method is affecting the value of StateVariable, CacheVariable, DiscreteVariable and not the object itself. This is now consistent with getOutputValue() and getInputValue() methods. Fixes issue #163.
Propogate rename to getStateVariableValue
Removed OLDconvertAngVelDotToQuaternionDotDot()

This method was removed and is a remnant of a stale Rotation.h that is being held in the OpenSim repo for the purpose of wrapping. This seems wrong and should be addressed in another PR.
