/*

Massselect written by aggelos katharopoulos

it has three callbacks
before , after and notmass

before: gets called before the add is done
after: gets called after the add is done
notmass: is called when we are selecting one and not many

currently there is no add operation and i know ehich are selected by their css class

CAUTION: i have occupied the onclick , onmousemove , onkeydown and onkeyup events of the document object
					if they are needed for any other script they can be found here and must keep backwards compatibility
