In this studio we will evolve our code from Render_Part_B_Assignment to add new methods and a new class.
Continue editing files in the render/assignment directory.

move
the move method will accept two parameters: direction and amount.
direction can be one of four symbols
:left :right :up :down
- left corresponds to translating along the negative x axis
- right corresponds to translating along the positive x axis
- down corresponds to translating along the negative y axis
- up corresponds to translating along the positive y axis
any other value for direction should raise an ArgumentError.
calculate_bounds
invoke calculate_local_bounds and transform the returned bounds by x and y.
NOTE: calculate_local_bounds is abstract. it must be defined by the subclasses.
