Detailed Description

This provides a base class to couple degrees-of-freedom within a single system.

This makes use of libMesh::DofConstraintRow as provided in libMesh::DofMap. For the $ k^{th}$ dof , $ u_k $, the libMesh::DofConstraintRow is defined as a linear equation

\[ u_k + \sum_{i=0, i\neq k}^{n-1} a_{u_i} u_i = b_k, \]

where, $ n $ is the number of degrees-of-freedom in the system. Note that a DofConstraintRow only requires non-zero $ a_{u_i} $ to be specified in the constraint.
