32e7429fd3
Major changes in data structures:
...
- Combined FieldAssembly and BoundaryAssembly to Assembly
- Combined FieldProblem and BoundaryProblem to Problem
- FieldProblem and BoundaryProblem are now abstract types
- Renamed stiffness_matrix, mass_matrix and force_vector to K, M, f for
easier notation
- Problems are no more abstract types but concrete types, see
elasticity.jl for example
- Combined linear_elasticity.jl and elasticity.jl
- Removed obsolete code directsolver.jl
- Almost all tests probably fail at this point
