Move parts of RamEcoreUtil to model project

[Matthias Schoettle]

The class RamEcoreUtil currently contains two kinds of methods. General ones to do on any ecore model and others related to edit functionality.

Move the general model operations to the model project (class could be called RamEcoreUtil in package ca.mcgill.cs.ram.util).

RamEcoreUtil should then maybe be renamed to RamEditUtil.
