Implementation of the default H(grad)-compatible FEM basis of degree 1 on Triangle cell.
Implements Lagrangian basis of degree 1 on the reference Triangle cell. The basis has cardinality 3 and spans a COMPLETE linear polynomial space. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:
