1/6/2014:15:01 - Begun work into building placement
1/6/2014:17:17 - Simple building footprint complete

Changes colour depending on if it collides with any other world objects
1/6/2014:21:22 - Building footprint recognises terrain
1/6/2014:21:46 - Pathfinding can show overlays depending on tile type

Temporarily changed in game.cpp by selecting num0-5
1/7/2014:01:35 - World Units begun

Can select by clicking a single unit, functions present to detect a
search of a FloatRect.  The positioning of world objects into the
collision grid is still finicky where if it is 32 x 32 for example it
will only check the top left corner, needs fixing
1/7/2014:13:23 - Test world unit complete

Has more accurate collision cell insertion, world object health begun
1/7/2014:16:49 - Simple world object selection complete

Can left click to individually select an object, or shift left click to
append another object, dragging a selection box selects all units within
it, and shift dragging adds all units within it
