* change default behavior so that dative bonds are not included in ring finding
* make sure that generating 2D coords does not lose the rings
* cleanup some leftover problems
counting the "on" bits in a bitset is a calculation - finding the
size of a std::vector requires only a lookup! For my example
system from https://github.com/rdkit/rdkit/pull/5654 , this
reduces the duration by another minute or so.
For an example large ring system, getSymmSSSR() took 3minutes.
After this trivial change, it went down to 2min 30s. I recognize
that's not much, but the change is _so_ minor I think that it's
still worth pushing.
Unfortunately, I can't share the structure :(
* add ROMol::atomBonds() and ROMol::atomNeighbors() methods
* remove some warnings
* start using the new code
* add default for those template params
* some more applications
* get the SWIG builds working
* get rid of extraneous ref
* remove extraneous comments
* Sped up SSSR by not storing every path back to root
This change speeds up ring performance by not storing
every path back to the root. Instead, it keeps track of
parents and rebuilds paths from the parents once a cycle
is found. It also stops the BFS once the depth of the BFS
is larger than the smallest ring (i.e., we found a path
that is longer than the smallest ring).

When finding rings - If we've exhaustively searched
an atom and found no rings, we should mark the bonds to
that atom as "not in a ring". We can also mark any
neighboring low degree atoms in the same way.
This speeds up searches in large molecules, because
a ring search that _doesn't_ find any rings is very
expensive, and it's a bummer to pay for that search
on two neighboring atoms, for instance.
RDKit sanitization is a bottleneck for some RDKit workflows that
I have. Particularly for large molecules, SSSR is pretty slow.
This improves speeds up SSSR from 6s to 2.5s for a protein that
I was looking at (3EOH). I think there is room for improvement,
but this is easy. Schrodinger's SSSR takes 0.02s for that same
molecule. (not a completely fair comparison, Schrodinger
doesn't use symmetrized SSSR).

* Issue #2403: Speed up SSSR symmetrization
For my horrible example molecule (a highly symmetric
nanotube with 2400 atoms and > 1000 rings), this speeds up
symmetrizeSSSR() from 5s to about 0.002s. findSSSR() takes
another .4s or so.

This makes Chem.SanitizeMol significantly faster when dealing with
molecules with lots of disconnected fragments (like a box of water).
The following is the runtime of Chem.SanitizeMol while adding 10,000
waters with explicit hydrogens when running Chem.SanitizeMol on every
1,000th water added.

* Refactor new_timings.py script a bit to be able to run only the first (reading molecules) test.
* Removing O(N^2) behavior of finding the number of bonds in the fragment during SSSR.
This only improves the case when there are long chains and a small
number of rings in the fragment. Many ring systems are still dominated
by the rest of the SSSR algorithm, and fragments with no ring systems
don't reach this part of the code.
For a test case with a single cyclicpropane and adding carbons while
calling Chem.SanitizeMol every 10,000 carbons added yield the
following improvement in performance:
before:
0 add_carbon = 0.00001s
0 Chem.SanitizeMol = 0.01237s

60000 add_carbon = 0.00181s
60000 Chem.SanitizeMol = 1.00577s
after:
0 add_carbon = 0.00001s
0 Chem.SanitizeMol = 0.01264s
10000 add_carbon = 0.00013s
10000 Chem.SanitizeMol = 0.01349s
20000 add_carbon = 0.00022s
20000 Chem.SanitizeMol = 0.02724s

60000 add_carbon = 0.00147s
60000 Chem.SanitizeMol = 0.08625s
Note, couldn't actually test a higher number of carbons as it led to a
stack overflow due to recursion in findSSSR.
Story: I have a PDB I want to read into RDKit. It has a disulfide bond
between two cysteines ~400 residues apart. This creates a very large
ring. RDKit throws an error because the number of found rings is less
than the expected number of rings. The ring wasn't found because RDKit
thought all "smallest" rings should be 256 or smaller.
Now, as long as your ring is UINT_MAX aka 4,294,967,295 or smaller, life
is beautiful. I hope no one has a ring bigger than 4 billion atoms.
o rdkit gains a RDKit::common_properties namespace that contains common string value properties
o Dict.h and below gain getPropIfPresent that attempts to retrieve a property and returns
true/false on success or failure. This is used to optimize access.
o rdkit learns how to pass property keys by reference, not value.
A new namespace has been added to RDKit, common_properties
that contains the std::string values for commonly used
properties. This helps to avoid typos in string values
but also avoids a creation of std::strings from character
values. All accessors (has/get/clear and getPropIfPresent) now pass
the key by reference.
Additionally, getPropIfPresent removes the double lookup
of hasProp/getProp which can be a significant speedup
in the smiles and smarts parsers (10-20%)
