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.
This function is sort of spaghetti's – I would break it to subsequent routines like "skip link" etc. Hard to read harder to maintain..
