* extend the allowed valences of the alkali earths
make it possible to have preferred and arbitrary valence states (I thought this already worked)
* backup
* maybe needed
* copy in some swig3 files;
at this point the tests all work
* remove SWIG version lock
* changes in response to review
* Fingerprint generator first prototype
* Added some more details to the prototype
* Update based on comments
* Added additional outputs and return type changes
* FingerprintGenerator updated and placeholder implementation added
* Added getFingerprint implementation to FingerprintGenerator
* Added comments for FingerprintGenerator
* WIP: Atom pairs fingerprint implementation for FingerprintGenerator
* Removed templates and added comments
* Fixed AtomPairEnvGenerator creating duplicate environments
* Added a atom pair old version compatibility test
* Moved the FingerprintGenerator related tests to a new file
* Added new comments and changes from the PR comments
* using int types from std instead of boost and remove cleanUpEnvironments
* Minor refactoring for atom-pair atom code generation
* Added more tests for AtomPairGenerator
* Removed additional clean up method from FingerprinGenerator
* Added additional output for atom-pair fingerprint and a test
* Removed leftover code
* Default argument changes
* Removed leftover include
* Default invariant generation logic seperated from env generation logic for AtomPairs
* Implemented fingerprint as bit vector type and added the test for it
* Folded fingerprint implementation and a test case added
* String representation for fingerprint generator is added
* Python wrapper for fingeprint generator added with a simple test
* Removed unused linked libraries
* AtomPair related wrapper code moved to its own file

* Fixed object lifetime problems for invariant generators in Python
* Fixed typo
* Added a list of test molecules and made fingerprint generator related classes noncopyable
* Morgan fingerprint python wrappers
* Removed argument helper class for wrapper
* Morgan Fingerprint simple implementation
* Added more invariants generators for Morgan
* Fixed a bug in Morgan bond invariant generator

* More documentation
* Python docs for atom pair
* Updated fingerprint generator notebook
* Python wrapper documentation added
* Seperated FingerprintGenerator implementations into seperated file again
* Python wrapper names updated to reflect new naming
