Defined GamePlayedTest, Modified GamePlayed

Modified the GamePlayed java class, now it does not assumes the 'x' or
'/' task as part of it's job, so, it just returns the exact values from
the read file for each player.

Defined the GamplePlayedTest JUnit Test Case class, for a single file.
UnCommented - in GamePlayedTest

Cahnged a test signature from 'testPlayers' to 'testPlayer1' according
to the task that's performed in that method.

Also unCommented the 'for' loop of the method mentioned before.
Finished Defining the GamePlayedTest JUnit

Completed the Tests for the GamePLayed class via GamePlayedTest JUnit
Test Case's. Tested with 2 diferente files located in my PC. and a
series of unit tests that test wrong to the file2 (there are 2 files:
file1, file2).
Insignificant: Uncommented a line

Just an uncommented line,
