Title: Add deep clone function for SpaceMap

We need to do deep clone of spaceMap. Cuz When we are doing planning, like "first we try to build a block in pos1 and then we destory the block in pos2", all these are only imagination, not really happen. So we are going to clone a spaceMap instance for this kind of imagination, like for planning.
