Each counter knows its format, and the IDs of anything it resets, as well as its value.

The features include registering new string formats for sequences, and 'chains' whereby some counters are reset when their parents. It keeps track of a number of 'counters', which are created on request: Usage:: >>> seq = layout.Sequencer() >>> seq.next('Bullets') 1 >>> seq.next('Bullets') 2 >>> seq.next('Bullets') 3 >>> seq.reset('Bullets') >>> seq.next('Bullets') 1 >>> seq.next('Figures') 1 >>> cCsi|_i|_|dSr) _counters _formatters_resetr8rrrr:s zSequencer.__init__cCs\|j|j|jtttttdt |j|jd}|j |j |d|_ dS)N)r/r0r1r-r.)rPrQ) rPclearrQupdater r)r,rrdict__dict___defaultCounter)r9drrrrRs     zSequencer._resetNcCs4z|j|WStyt}||j|<|YSw)zCreates one if not present)rPKeyErrorr2)r9r?cntrrr _getCounters   zSequencer._getCountercC|s|j}||S)z_Retrieves counter value but does not increment.
