* 3256: Envelope aromaticity not detected in complex fused system
Removes stopping point in aromaticity detection when all atoms
are "done". This also markedly improves the performance of
aromaticity detection for very large molecules - for example,
aromitization of 3EOH from the PDB was dominated by done atom
checking before this commit.
Some aromatic bonds were missed before this commit in complex fused
systems. This happened if all atoms in the fused system were also
in some smaller aromatic ring and there was at least one fused edge
that was single in the kekule form.
Some example molecules for which envelope aromaticity failed
before this commit:
c1cc2n(c1)c1cccn1c1cccn21
-> became c1cc2n(c1)-c1cccn1-c1cccn1-2 before this commit
c1cc2c3cc[nH]c3n3cccc3n2c1
-> became c1cc2n(c1)-c1cccn1-c1[nH]ccc1-2 before this commit
c1cc2c3cc[nH]c3c3cc[nH]c3n2c1
-> became c1cc2n(c1)-c1[nH]ccc1-c1[nH]ccc1-2 before this commit
Here's a similar example that didn't fail even before this
commit. The central ring only shares double bonds with the
exterior rings.
* c1cc2c([nH]1)c1cc[nH]c1c1cc[nH]c21
Requires updates to some MQN descriptors tests because some
bonds become aromatic (MQN includes counts of single and
double bonds of kekule form).
FWIW, for the molecule that had a change in counts, the counts
were incorrect both before and after this commit, because
MQN uses an approximation (dividing aromatic bonds evenly
between single and double bonds) to avoid kekulization.
This approximation is invalid when there are oodles of
nitrogens lone pairs participating in the aromatic
bonds.
(the failing line was 2558 in aromat_regress.txt: Cc1cc2n(n1)c1cc(C)nn1c1c(C=O)c(C)nn21)
* Detect envelope aromaticity in fused systems
In #3253, we proposed removing doneAtoms for performance, and it was
noted that it also fixed detection of envelope aromaticity in some
fused systems. However, when I completely removed doneAtoms, I saw
hangs in sanitization of things like nanotubes. Using doneBonds
allows envelope aromaticity, while preserving a reasonable break
on runaway work for crazy molecules.
The performance issue was addressed by caching the ring bond
count.
Here are some sanitize timings on proteins from the RCSB PDB:
Before this commit:
* 3eoh 1.21s
* 2j3n 0.77s
* 1nks 0.053s
Afterwards:
* 3eoh 0.42s
* 2j3n 0.15s
* 1nks 0.046s
* Use boost::dynamic_bitset instead of unordered_set
To cound ring bonds.
* Stop trying to assign hybridization to actinides
There's also some cleanup in this commit
* Apply suggestions from code review

Fixes removeHs removing Hydrides by adding a removeHydrides flag to RemoveHsParameters.
If removeHydrides is false, Hydrogen atoms with formal charge -1 and degree less than or equal to 1 are kept
removeHydrides is kept true by default
* Made suggested changes
Removed extraneous comments and redundant code
Added tests for both ```removeHydrides = true``` and ```removeHydrides = false```
Added tests that ```removeAllHs()``` also removes hydrides
Exposed ```removeHydrides``` parameter to python
* Explicity Added removeHydrides=true in removeAllHs
Corrected typo for removeHydrides
* make formatting consistent
