    /*
       sequence
    
       Iteratively performs an action while refreshing the state of the visualization.

       Parameters:

       options - (object) An object containing some sequence options described below
       condition - (function) A function returning a boolean instance in order to stop iterations.
       step - (function) A function to execute on each step of the iteration.
       onComplete - (function) A function to execute when the sequence finishes.
       duration - (number) Duration (in milliseconds) of each step.

      Example:
       (start code js)
        var rg = new $jit.RGraph(options);
        var i = 0;
        rg.fx.sequence({
          condition: function() {

   - <Options.Edge>
   - <Options.Label>
   - <Options.Events>
   - <Options.Tips>
   - <Options.NodeStyles>
   - <Options.Navigation>
   
   Additionally, there are two parameters
   
   levelDistance - (number) Default's *50*. The natural length desired for the edges.
   iterations - (number) Default's *50*. The number of iterations for the spring layout simulation. Depending on the browser's speed you could set this to a more 'interesting' number, like *200*. 
     
   Instance Properties:

   canvas - Access a <Canvas> instance.
   graph - Access a <Graph> instance.
   op - Access a <ForceDirected.Op> instance.
   fx - Access a <ForceDirected.Plot> instance.
   labels - Access a <ForceDirected.Label> interface implementation.

  Description:
  
  ForceDirected algorithms can perform many computations and lead to JavaScript taking too much time to complete. 
  This method splits the algorithm into smaller parts allowing the user to track the evolution of the algorithm and 
  avoiding browser messages such as "This script is taking too long to complete".
  
  Parameters:
  
  opt - (object) The object properties are described below
  
  iter - (number) Default's *20*. Split the algorithm into pieces of _iter_ iterations. For example, if the _iterations_ configuration property 
  of your <ForceDirected> class is 100, then you could set _iter_ to 20 to split the main algorithm into 5 smaller pieces.
  
  property - (string) Default's *end*. Whether to update starting, current or ending node positions. Possible values are 'end', 'start', 'current'. 
  You can also set an array of these properties. If you'd like to keep the current node positions but to perform these 
  computations for final animation positions then you can just choose 'end'.
  
  onStep - (function) A callback function called when each "small part" of the algorithm completed. This function gets as first formal 
  parameter a percentage value.
  
  onComplete - A callback function called when the algorithm completed.
