Create a foundation for Token Parsing

[Tom Hancocks]

The compiler needs to parse a stream of tokens and identify syntactic structures within it. At its most basic it needs to be able to do the following:

• Identify and expand import directives
• Identify function declarations
• Identify function definitions
• Identify code blocks
• Identify type information
• Identify symbol information
• Construct an Abstract Syntax Tree
• Construct a Symbol Table

The bare minimum should be built for this to allow for the target Hello World executable and basic standard library imports required in this version to be met.
