// Set the UI in sequencer. This Will generate HTML based on

|
// Image Sequencer events :
|
|
// onSetup : Called every time a step is added
|
|
// onDraw : Called every time a step starts draw
|
|
// onComplete : Called every time a step finishes drawing
|
|
// onRemove : Called everytime a step is removed
|
|
// The variable 'step' stores useful data like input and
|
|
// output values, step information.

// See documetation for more details.
