docs/model-module (#13)

* docs(model/entities): Documentation for entities and items

Adds documentation to the following entity and item classes
    - Entity
    - EntityUtils
    - Items

Did not add documentation for Ghost entity and Pacman entity,
since the class is not done yet.

* fix/small-fixes (#14)

* fix(model/entities): entites start in center of tile
* style(pacman): It should be width and height, not height and width.
* refactor(view): Changing setting of background color
