[IN PROGRESS: Implementing Database 'select' feature]
-------------------------------------------------------------------------------
Project Overview:
This is Project 2 from UC Berkeley's CS 61B (Spring 2017 by Professor Josh
Hug), a massive capstone project in which you use Java to implement a
relational database management system that a user can interact with via a
language similar to SQL.

I learned how to:
1.) Design and implement a Table structure by experimenting with different
data structures (maps, lists, sets, arrays).
Final design:
LinkedHashMap<Integer, LinkedHashMap<String, String>>
See Table.java for more details.
Flawed design attempts:
a.) String[][]
b.) HashMap<String, ArrayList>
c.) LinkedHashMap<String, LinkedHashMap<String, String>>
This one has a subtle difference from the final design, but
its use is too complicated to explain and eventually becomes a
nasty problem in the join() function.
2.) Set a standard table format (.tbl) and parse through it to add data to
a database.
3.) Implement a database and the corresponding management features.
4.) Parse through and put into effect commands that the user inputs to
interact with the database.
5.) ...

Notes to self:
1. Stop using == to compare Strings. You must use String.equals().
