OLPCities/Mouse over and click

There are two very usual resources that are used when we are working using Sprites: the "mouse-over" and the "mouse-click".

The Class Sprites has four properties that we use:

onmouseover [=String]         The string is the function name to be called when the mouse
                              pointer has moved over the sprite. This CAN include arguments so
                              mySprite.onmouseover="dosomething(x,y,z)" would pass the variables x,y,z 
                              to the function dosomething  

onmouseout [=String}         The string is the function name to be called   

onclickdown [=String]        The string is the function name to be called  

onclickup [=String]          The string is the function name to be called
