   1. Read a File and Split the lines
   2. For each line read character by character
   3. Concatenate characters, creating the largest STRING possible. Stop
   when a delimiter, white space, operator, or quotation mark is found. If
   there are more characters in the line, go to step 2.
   4. Bonus points: for each STRING report its TYPE as correspond. E.g., class
   is a keyword, { is a delimiter, hello is a name (identifier), Student is a name
   (identifier), + is an operator, extends is a keyword, etc.

    § Interface declaration
    § Class declaration
    § Inheritance (from 1 class)
    § Realization (implements) from multiple interfaces
    § Variables global
    § Variables global (that are not null)
    § Methods
    § Variables Local
    § Call methods (using an abject or class name)
    Task
    Assume a good user that never never never make mistakes. Thus,
    it is not going to extends from an interface or implements from
    a class
