Changed 2 arrays into Enums in unit and button. Added doxygen documenation for : Archer, Button, DamageCalculation, Game, GameState, HowToPlay,HowToPlay2, HowToPlay3, Mage, Unit, Warrior

Units now take damage upon attacking, and getting counter attacked. Enemy units now have a counterattack animation

Attacking now works. Changed MenuButton class to Button class, incorporated attackConfirm button with other buttons. Wrote function determining whether enemy unit is in range. Fixed a lot of attacking logic.

Added assets for player turn end, attack button for attack sequence, and replaced character stats to allow for larger font

Clicking attack now leads to a new state, where a user can select a unit to attack. Added attack confirmation button in this state, where an attack will only execute after confirming

Added another mainMenu state - attackConfirm. Added dif directions for attacking. NOw detects what unit is being attacked. WORK IN PROGRESS
