<p>With this class you may select which of a number of cut procedures to use on the fly. The selection is from an array of BBCutProc derived objects (which might include a further MultiProc!). The index is chosen on a per phrase, or per block basis, by passed valid index returning functions. If a blockfunc is provided, then the selection is always per block. Otherwise it is per phrase. Note that for convoluted switches between many cut procedures at block rate it becomes very unpredictable when phrases start and end, since multiple phrases are bundled together at once.<h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
