gridRaycast()

template<typename Action_T >

void gridRaycast	(	Action_T &	quadAction,
		const btVector3 &	beginPos,
		const btVector3 &	endPos,
		int	indices[3] )

Iterates through a virtual 2D grid of unit-sized square cells, and executes an action on each cell intersecting the given segment, ordered from begin to end. Initially inspired by http://www.cse.yorku.ca/~amana/research/grid.pdf
