* the boundary will be assumed to be those vertices constrained to
* a domain less than or equal to the specified dimension (I.e.

*\param depth The number of elements inwards from the boundary for
* which all contained higher-order nodes will be free
* variables in the optimization. Any vertex for further
* from the boundary will be slaved. Specifying zero
* will result in all higher-order nodes being slaved
* except free nodes on the boundary.
*\param max_boundary_domain_dimension Specify the definition
* of "boundary". If greater than or equal to 4, then
* the the set of all fixed vertices is assumed to be
* the boundary. If less than four, then all vertices
* constrained to a domain with the specified number of
* fewer degrees of freedom (constrained to a geometric
