Function
* The Sequencer offers an animation sequence control.
  Details on the sequencer will be described using the MhcSeqInst Structure.

Function
* void mhcSequencerInit( MhcSequencer *seq_ptr,
			 float *index_ptr, float *time_ptr,
			 void *user_data )
  Initialize Sequencer

* void mhcSequencerExecute( MhcSequencer *seq_ptr, MhcSeqInst *inst_ptr )
  Specify execution instruction.
  At this point the Sequencer stops the instruction currently being executed, 
  calls on_stop, and executes the new instruction.

* void mhcSequencerProgress( MhcSequencer *seq_ptr, const float step )
  Using step advance the sequence by time shown only.
