public abstract class Selector
extends Object

A selector takes a formation and pulls out all instances of a selected sub-formation, numbering the dancers in each in a canonical order. (We've given names to common numberings.) For example, given facing lines, the FACING_COUPLES selector would extract the two instances of facing couples, and number the dancers in each facing couple 0-3. Each instance of a facing couple could then be decomposed into two FACING_DANCERS (numbered 0-1).

public abstract FormationMatch match(Formation f)
                              throws NoMatchException

Select sub-formations from a formation using this selector. (The subformation may be as large as the original formation -- or even larger, if phantoms are generated; it may also be as small as a single dancer.) If the given formation can't be selected from the current dancer configuration, throws NoMatchException.
