Detailed Description

LocalToGlobalMap class: map the local degrees of freedom of each Element to the global ones.

The Local to Global map is strongly dependent on how the program that utilizes the Element objects is organized. The objective of this class is then to define the interface that the derived objects should have.

There will generally not be a single LocalToGlobalMap object per Element, but rather only one LocalToGlobalMap for all of them. Hence, the interface requires a way to specify which element is being mapped.

Convention:
Fields and Dofs start to be numbered at 0
