David Cosgrove fcc2e226ff Get started c++ (#1285)
* Start of GettingStartedInC++ documentation.

* Changed GettingStartedInC++ from rst to markdown format. Added some more text.

* Added Working with Molecules to GettingStartedInC++

* Expanded on behaviour of Kekulize wrt clearing aromatic flags on atoms and bonds.

* Added section Modifying Molecules.

* More plodding progress.

* A load more documentation.

* Undid change to global CMakeLists.txt

* Minor editing of docs.

* Changed examples so they use RDBASE to find test data rather than relative
path.

* Fixed use of -std=c++ in CMakeLists.txt. Extra waffling about memory.

* Modifications to examples and documentation as requested.

* Couple of minor changes.

* Change to example11.cpp and associated text in docs.
