* boost::thread mostly gone... still need to get rid of once
everything compiles
* replace boost::call_once
* remove link-time dependency on boost::thread
* first pass at using async
* switch to using async everywhere
* add a SmilesParserParams object to prepare for this
* add a SmilesParserParams object to prepare for this
* add tests for the SmilesParseParmas
* support name parsing, should it be the default?
* rename CXNSmiles to CXSmiles;
add a spirit parser for CXSmiles coordinate that is at least syntax correct
* abandon boost::spirit for now; crude atom token parser
* support params in smiles parser (not tested, may not build)
* can read coords and atom labels along with mol names; crude, but works
* read coordinate bonds
* remove some compiler warnings with VS2015
* remove a bunch of compiler warnings on windows
* remove more warnings on windows
* remove more warnings on windows
* backup commit: first pass at parsing query features
* radical spec parsing
* handle attachment points using atom mapping
* switch to a named property for atom labels
* fix handling of the "A" atom query
* add functions to construct A and Q queries (needs more work)
* fix a problem created while cleaning up warnings earlier
* add some additional convenience functions for making generic atoms.
Still need M and to recognize these while writing CXSMILES
* add M queries; update some tests
* fix a linux compile problem
* get the cxsmiles stuff working in python; basic testing
* support "M" in CXSMILES
* first pass at a MultiFPBReader in c++
includes initial tests
* first pass at multi-threading; untested
* add multi-threaded test
* multi-threaded tversky
* add multi-threaded contains searches
* allow FPBReader::init() to be called multiple times
* add a cleanup() method to clear out whatever memory we are using
* allow the init() call to be pushed to search-time;
this allows calls to the contained init() methods to be run in separate threads
* make ownership of FPBReader pointers optional
add addReader() method
* Add MultiFPBReader python wrapper
* support multi-threaded initOnSearch
* add a couple of more tests
