* #include an absolute path didn't work - because paths were taken to always be relative.

* Improve diagnostic for token pasting.

* Token paste location test.

* Output include hierarchy.

* WIP on includes hierarchy.

* Improved include hierarchy output - to handle source files without tokens.
Improved test case.

* Small comment improvements.
Fixed a typo with not returning a reference.

* Slight simplification of the ViewInitiatingHierarchy, by adding GetOrAddValue to Dictionary.
