Test commit. Commented out davidson diagonalization.
Finite algorithm, with problems. Energy in finite sweeps gets more positive rapidly.
fixes the crash issue but the code is still wrong.
Fixed the problem! Had to do with a transpose order thing.
Re-wrote finite DMRG to be more object oriented. Now does several sweeps with increasing basis size.
Whoops, forgot to include the new block class in the previous push.
Made the print graphic function slightly more concise.
Adding dsyevr routine to calculate selected eigenvectors
Problems with dsyevr.
Working dsyevr! Speeds up pretty noticeably.
minor fixes
Merge master branch with finiteDMRG-BAA
