This PR basically adds a function called
obtainLagrangeNodePositions
that helps to obtain the global positions of the Lagrangian nodes. This is adapted from the Dune book (Section 8.3.1). This can then be combined with the member functionfixIthDOF
of the classDirichletValues
to fix particular DOFs. This mainly helps if in case the user uses higher order elements with nodes living on the middle of the edges of elements, for example, to be fixed.
