bool operator< ( const Region & other ) const

Compares areas of two Regions; really only used to sort Regions assumes area already calculated Notes that it actually returns greater-than instead of less-than, so that lists are sorted with biggest areas first

void recomputeProperties ( )

sets all properties to be NOTCOMPUTED called after making changes (either addition/deletion) to table
