Dev-log Day 2:

Today started with creating containers for game entities, with the assumption that all entities will have a 2x2 meta-sprite.
these containers added extra components for handling entity collisions and auxiliary functions that can be used by any entity (not just the player).

After this, I had to re-design the animations, as they are specific to an entity, and the definition itself shouldn't really hold the references.

Once that was done I put in code to check if an entity can move, presently hard-coded to a single tile type,  TODO: Enable a set of walk-able tiles.
