* Fixes a molblock writing problem
with undervalent atoms from the organic subset
* Fixes#2649
Also ensures that allenes are not written as crossed bonds
(which does not make sense at the moment anyway)
* clang-format run
* add AtomValenceException
* refactor a bit and add KekulizeException
* add copy ctor and copy() method
* add detectChemistryProblems
* add getType() method
want to be able to get the type of the exception without requiring doing a bunch of dynamic casts
* first pass at exception inheritance/translation
needs some cleanup and expansion, but this does pass all tests.
* cleanup and finish the python wrappers for the new exceptions
* make sure things are truly polymorphic
* wrap shared_ptrs of the new exception types
* expose DetectChemistryProblems()
* get the java wrappers building again
* transfer those changes to the c# wrapper
* add detectChemistryProblems()
and deal with the fun fun exception inheritance things that ensue
* response to review
* Fixes#2437
getting the canonical atom ranking no longer results in molecules have a
RingInfo structure that's been initialized but contains nothing.
* update expected results for the MMPA tests
* not quite done yet
* Fixes#2244
* Fixes#2148
This fixes a few of the knock-on effects of the actual fix.
* Test that we still write SMILES properly
* Fixes#2266 (#2269)
* Fixes#2268 (#2270)
* Improve interactivity of output SVG (#2253)
* Add clickable atoms when tagAtoms() is called
* add python tests
* add class tags for atoms and bonds
* add marker to allow easy insertion of extra text
* Modify removeHs so that it does not remove degree 0 atoms
Update the docs at the same time.
* include a warning when not removing some Hs
* clear up a problem with the warning log
