Source File Reader and Reader Creator for Parsing

[claytn]

Changes Made:

• Removed the reader.js file in root directory and added its contents into the index.js file (the starting point of our application)
• Added a parser_reader file within the parser folder. This is in charge of creating an array of reader objects that correspond to the array of files given to it. I may move the Reader object declaration info into a separate file, but it sits here for now.
• Added a Test_Web_Project folder with tests. This will just contain example html docs to use when we are writing the parser.
• Added tests for the existing Reader functions.

SideNote: The implementation for some of the methods I've written for the Reader may change based on the functionality we need most for the parser phase.

Don't approve this just yet. I started messing around with that pattern matching library and I think I'd like to move some of this logic outside the reader and into the parser itself. The reader was hiding too many details of its own for things like getTag and that should be able to be seen within parser similar to how it was for the miniscala compiler.

I'll merge another branch into this one soon.

Yeah I like that train of thought. I was kind of thinking along the same lines
