New sub-module: DiscreteModeling

[miguelmaso]

Helper functions have been moved to this module, to avoid messing-up the ComputationalModels.
Theese functions are not a computational model because does not involve weak forms, neither solvers.

• Moved EvolutionFunctions to DiscreteModeling
• Moved CartesianTags to DiscreteModeling
• Moved FaceLabeling to DiscreteModeling
• Added MeshDescriptor to DiscreteModeling
