Detailed Description

It helps meshers to add elements and provides other utilities.

It allows meshers not to care about creation of medium nodes when filling a quadratic mesh. Helper does it itself. It defines order of elements to create when IsQuadraticSubMesh() is called.
It provides information on a shape it is initialized with: periodicity, presence of singularities etc.
