Working towards an improve description of the enrichment domain.
Added class EnrichmentDomain to support discontinuity description using a list of dofmanagers.

+ Started adding methods in Shell7BaseXFEM to handle the xfem contributions.
Added some methods to Shell7BaseXFEM
stash
Moved initialization of xfem to domain
Working on methods to create new enrichmentdofs in a flexible way for XFEM.
Small fixes to reduce compiler warnings.
Incremental changes
+ Method to compute the solution vector for a given enr.domain

+Method to compute the disc. part of the base vectors
Small restructuring
Working with extraction of dofs
Modified beSubArray but need to fix rcm2 as this was the only file suing the method
