remove of detail/ directory and ::detail namespace, now all is in ::lss. added a pure method to linearsystem to initialize system matrix based on an index_t object. related changes to all solvers.
fixed small bugs in MatrixMarket reading/writing, compression/uncompression supported in sparse matrix, slightly simpler matrix interface to the solvers. cleanup of read_desnse functions in utilities.
trying to make consistent the internal matrix structure, this is a "restore point" before turning the sparse_matrix into a double-personality (coordinate-compressed) structure
testing some stuff
added a schizophrenic personality to the sparse matrix: it alternates between compressed/uncompressed states as necessary. this is a bit based on Eigen, maybe I should have used that instead.
updated pardiso to this new sparse matrix
updated to this new sparse matrix

updated to this new sparse matrix
cleanup
something is now working in Muphys, these are the changes to the core lss plugin
non-working dlib-based linear system solver, not working yet
related changes to lss implementations, some testing is still required
Merge pull request #15 from pmaciel/master

lss solvers are working inside muphys, though i don't like how it looks like in there...
