Detailed Description

A strange but true thing to make copying from one boxlayoutdata to another fast.

class to handle the of data from a LevelData to a BoxLayoutData defined over the same index space. The idea behind this object is twofold: A) there is a significant amount of information that can be computed once and reused from one copy to the next for a LevelData and BoxLayoutData that have unchanging BoxLayouts underneath them. In these cases, LevelData::copyTo methods has an optional argument. That way, in cases where the operation is only performed a single time, we do not waste our time building optimizing data, etc. B) when we interface with KeLP, this class maps quite well with the existing KeLP API.

pains have been taken to not have this class be templated. Thus it does not actually perform the copying itself (which would require knowledge of the template class type). It provides an iterator interface to MotionItems that specify the required work. LevelData provides the copyTo methods.
