CHANGES TO CONQUEST.JAVA
Added support for turn rotation (see below).
Changed Player1 and Player2 strings (denoted by "string" prefix) to
public and static variables to allow changes from other classes.
Added JButton btnEndTurn, that rotates player turns.
Main method now calls the ConquestStart class before doing anything
else.
Added ActionListener to btnEndTurn. Calls the changeTurn() method. See
below.
Added changeTurn() method. Method toggles the boolean value
booleanIsPlayer1 flag depending on its previous value, then resets the
selected unit flag to prevent accidental moving.

CHANGES TO CONQUESTMAP.JAVA
Added a coordinate system for units (not yet functional).
Added a coordinate occupied flag system (not yet functional)
Added moveTest() method (for testing purposes only, will be removed in a
later update).
Fixed Player 2's units taking the location values of Player 1's units
Added initLocations() method. Associates the appropriate window location
with the coordinates. Not yet functional.
Added initUnitCoords() and initGridOccupied() methods. Not yet written.

CREATED CONQUESTSTART.JAVA CLASS
Description: Creates a JDialog window where the players enter their
names before the game starts.
Contains:
Textfields for entering player names (denoted by "txtfield" prefix):
Player1Name
Player2Name
Added buttons for exiting, starting the game, and instructions on how to
play (calls the ConquestHowToPlay.java class)
Clicking on btnStartGame button will call the getNames() method, which
ensures the names are less than 30 characters (to prevent the name from
overflowing their allotted space. The method then calls the rollDice()
method (see below) before closing the window entirely to start the game.
Added rollDice() method. This calls the RandomIntGenerator method (see
below) which generates a random number between 1 and 6 to see who goes
first. The one with the bigger number goes first. Also contains a check
whether both players tie. If this happens, the "dice" is rolled again.
Added RandomIntGenerator() method, which generates a random number in a
set range depending on its set parameters when it was called.

CREATED CONQUESTHOWTOPLAY.JAVA
Description: This class is called from the ConquestStart.java class
only. It is a JDialog window. The window displays instructions on how to
play the game.
Contains:
JButton which closes the window.
Placeholder for instructions. Will add more details once game is closer
to completion.
