added some constructors
added basic movement actions.
teleport is suposed to move somthing to always the same location.
move is suposed to add difference to the current location.
comment of previous commit was better then the comment in code, so I copied & pasted it in code
moved better comment to the interface & added a see
added some cubes to glare at all day...

Well they have a function. I get desorientated quite easaly in game & the cubes let me see somthing, it works less nausiating, even if they are so bright & colorfull.
