related to that cell (since elements are usually temporary and so kept in a separate list, not in the cell). Corrected a major error in the bplane implementation that failed to remove a cell use from the child def's parent list when deleting the use. Can cause magic to go into an infinite loop, especially after selecting and unselecting cells.
TODO ---- NOTE: nested enums are broken do to dynamic binning. Don't rebuild entire bplane when bbox grows. unsubbing sometimes. Some (remaining) bplane design issues: groups? idea: support small number of groups by having separate bplane for each group. Do selection this way. Logically layered on top of bplanes - but may want to integrate. DECISION: defer for now. pack/unpack? Seems incompatible with user alloc/dealloc. Complicated. DECISION: Forget it. coarse/fine with cache. can be added later. should fit in nicely. no special support needed. integrated find/add? can add later. don't worry about it now. May want to add attributes, via external hash.
