Restructuring of Matrix and Vector and linear-algebra backends

Summary

Restructuring of Matrix and Vector and linear-algebra backends

Details

• Restructuring the vector and matrix backend wrappers
• Added init-finalize also for vectors
• Require gather/scatter operations instead of direct vector/matrix access
• Rewritten the interpolation
• Added ParallelIndexSet and DOFMapping to be used also in other backends
