* add reference input/output files for yaehmop
* orbital energies, overlap matrix, and hamiltonian on the C++ side
* add the python wrappers for the new functions
* stub for YAeHMOP integration
* switch to using catch for the test
* first steps towards calling from rdkit
* switch to using some smart pointers
* runs, but has unpredictable seg faults. Needs valgrinding
* cleanup
* allow hacky linux builds too
* start using unique_ptrs for memory management
* don't find princ axes by default
Support probably isn't compiled in.
* save computed properties
* additional cleanup
* start working on a smarter way to get the code
* start making the cmake externalproject support work
* seems to work
* does not work yet
* this actually seems to build and work on linux
* theoretically more robust
* handle the parameter file
* first wrapper
* try to get mac builds working too
* initial pass at including reduced charge and overlap population matrices
* update docs
* backup commit
* switch to using cmake to handle the C++ spec
* switch to using a results object for the eHT calculations
* support fermi and total E
