forgot to add morse cpp potential to setup.py
add some comments and documentation
remove pydev .project from repository
clean up th c++ lbfgs.h a bit
add some comments
Fixed group_rotation_file function to add 1 to each index (since Fortran
counts from 1, not 0).
fix indenting
Merge branch 'master' of github.com:pele-python/pele
fixed compile tie bug in Array::view

might have been visual studio specific
Merge branch 'master' of https://github.com/pele-python/pele.git
change name interaction list to neighbor list

also, add a test for LJNeighborList potential
atom indices are now passed to the interaction objects

_interaction->energy(r2, atomi, atomj)
_interaction->energy_gradient(r2, *gij, atomi, atomj)
created source/wca.h, source/hs_wca.h, pele/potentials/_wca_cpp.pyx. Testins is required yet
fixed hs+wca potential, not compiling yet, requires change in simple pairwise potential class
implemented PairwisePotential which unlike SimplePairwisePotential passes the indices of the particles for which the interaction energy is being computed, this allows one to calculate the pairwise potential of polidisperse particles that depens on their relative sizes. Also implemented HS_WCA class for the HS+WCA potential and its cython wrapper
some changes to tests and _hs_wca to find bugs
bug fix in gradient of hs_wca potential
