Change the code coverage to green. * removed duplicate code * Removed unused code * removed unmaintained code * DCTI + DVTI refactored * discrete fields refactored and tested * fields are now tested quite well. * Removed obsolete code not used anywhere * Element descriptions to common dictionary * size in global const dictionary also * Added coverage to sparse tools and removed couple unused functions * get nonzero rows from SparseMatrixCSC * bugfix: extending element basis now working and tested * Removed two unused functions from elements.jl * removed useless function * Useless conversion * remove elasticity assembly using ForwardDiff because it's not used anywhere' * Added basic testing for NURBS. Fixed bug in NSolid interpolation. * removed unused functions * Removed some debug stuff * renamed file * removed field assembly posthook, i think not good idea at all * test for nnz(K) == 0 and automatic determination of dofs * Testing that solver is throwing error if having problems with boundary assembly * Removed some unused options. Refactoring. * Moved solver non-related code to elements.jl * Removed custom exception (no need) * unneeded postprocess code * More tests for NURBS elements. * Removed unfinished .mail parser * proper use of Logging package * also read results * renamed test file * create_surface_elements accepts surface name in String now * bugfix: remove zero rows from constraint matrix after manually removing dofs from some boundary assemblies. * New test, displacement 3d patch test * skip displacement field in surface element splitting if not defined * test element splitting and linear surface elements, fails. * Bugfix: Xdmf, not XDMF * removed nonworking tests, requires bugfix * abaqus_read_results is not working -> bug
