Author: Benjamin Walter Newhall, 12/17/19, github: bennewhall Explanation: much like the data sources class, this stores type data in the form {“variable-name”=>String}

Author: Benjamin Walter Newhall 12/17/19 github: bennewhall Explanation: A class that holds the types used for the validator

Author: Benjamin Walter Newhall 12/17/19, github: bennewhall Explanation: A class that will either return the ending type of an ast, or throw an error with metadata information about error position Usage: v = Validator.new(typesource) (typesource is a TypeSources object)

v.validate(ast)                     (ast is the ast returned by parsing a line)(this will either return a type or throw an Error as described in the errors.rb file)
