MSON Utility functions

Added an MSONUtility file which contains the following functions:

* parseValue
* parseSymbol
* parseTypeName
* parseTypeAttributes
* parse TypeSpecification
* parse TypeDefinition

Also adds `StripMarkdownLink` function to StringUtility file.
Please define `*` and `_`  somewhere in one place? Maybe markdown parser etc. So it it clear we are talking about Markdown emphasis characters. I have the impression that these *magic* Markdown "constants" will be popping up during the code more and more
