Added axis_ and renamed axes_.
Added axis_, which is an array that will be used to store tiles' X and Y coordinates, and renamed axes_ to split_axes_, to avoid confusion.
Furthered Acre::render().
Changed axes_ to split_axes_, to make clear the variable's purpose. Also implemented axis_[0] (X) and axis_[1] (Y), which stores the X and Y coordinate values of loaded tiles.
Corrected array typo.
The axis_ array was written as axis[2]_ instead of axis_[2]. This was corrected.
Fixed typos.
Acre::render(), on line 72, called for enums which didn't exist. Also, "split" was misspelled.
