* stop using CIP codes in the atomic canonicalization
this will change results in some cases, so lots of tests need to be updated.
* stop breaking string literals... ARGH
* tests now pass
* update double bond canonicalization
* update a python test
* some cleanup
* update expected results for cartridge
* Nonchiral atoms should be removed from StereoGroups
This fixes a bug where atoms which have no chirality were left in StereoGroups
In order to make this work, ROMol::setStereoGroups() needed to be made public.
That shouldn't be a problem since it doesn't change connectivity.
* support CXSmiles extensions in the hashes
* initial tests for that
* some cleanup
* copyright header cleanup
* minor refactoring
* call out the changes in the release notes
* extension and more testing
* add python wrappers
* a round of cleanups courtesy of PVS studio
* add a test to make sure that a warning is a false alarm
* bug fix
* Fix a UFF bug
* more PVS studio cleanups
* next round of PVS studio cleanups
* completely remove the chances for that bug
* changes in response to review
* add an additional test
+ a bit of reformatting that snuck in
* do not remove multiple bonds that aren neither conjugated nor to heteroatoms
* unflag aromatic bonds
* remove bond stereo too
* call assignStereochemistry after the tautomer normalizations
* copy in, get building, add some basic tests
* complete the testing
Except for regiosiomers, which do not work
* regioisomers work now
* backup commit; things work
* remove last of NM macros from hashfunctions.cpp
* remove last of NM macros from hashfunctions.cpp
* remove dependency on the abstraction layer
* typo
* start using namespaces
clang-format
* switch to using enums for the HashFunctions and StripTypes
* Add initial python wrapper (and tests)
* move the new hashing code to the MolHash library
still may want to revise the naming of this
* Setup deprecation of the older hashing code
* better release notes text
* change in response to review
