Add Semantic Versioning starting Version 1.0.1.dev

[MathewBensonCode]

• Bump patch version
• Introduce Semantic Versioning

Should close #518

Observations

• The CMake Project command only accepts integers for the versions. Hence the use of 1.0.1.0 in the project command.
• It appears that the tagging of the Version commits will have to be done on the branches by those with write access as I don't think tag information carries over via pull-requests.
• Therefore creating the Version Change Commits and tags would be the responsibility of the maintainers as would the process of determining the level of change required.

based on the discussion happening here #518, I think it should be 0.2.0
