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.
Well, No one would use something like this, right? It's a markdown link inside a markdown link. I don't think any markdown parser implemented support for this.
