Modified filename in matlab export
removed file
Small updates in Shell7
Extremely simple implementation of a constrained Newton. If the residual does not decrease between iterations a smaller update is used x_new = x_old + alpha*dx.
Revert "removed file"

This reverts commit e49b280bf5c8516b0bb35b686f5065f25f298912.
Added postInitialize to XFEM manager, enrichmentItem and enrichmentDomain
Added some export for sets in MatlabExportModule

Modified Shell7BaseXfem such that the discontinuous dofs are scaled with a factor 1e-3 in order to hopefully reduce the condition number when using cohesive elements. This needs to be evaluated.

Scaling of discontinuous dofs seems to be working correctly
Added instanciateYourself in EnrichmentDomain in order to use a node set to define the nodes in dofmanlist

Started to implement through the thickness cracks for Shell7BaseXFEM
