Detailed Description

Builds the trace space of an FE space.

The elements are from type hp2D::Edge.

One can restrict the trace operation by cell conditions.

If the FE space is rebuild, one has to construct the trace space again.

Additonally a map from the topological edge to the set of the underlying elements is stored.
