basic map with random markers showing on it

This sets up a basic map and marker that will show up on the map.

components.js:
--this file includes the two components (map and marker) and their associated properties

scenes.js:
--this file sets up the map scene
--this scene includes one map component with 5 randomly places marker components

game.js:
--this file loads the game and first scene (which is the map scene)

All this does so far is generate five random markers and put them somewhere on the map.  Hopefully this is a start and we can move towards putting markers in specific locations and moving between them.
