docs: Open a parameter collector suitable for collecting information about a command.
  Once a collector is created, the specified function is used to fill it with
  information needed by the command.  This method is used for commands that cannot
  rely on a simple parameter description to collect parameters.  Commands that describe
  their required parameters do not need to use this method because the command framework
  will open and close parameter collectors as needed and call the command callback with
  the values of those parameters.
  
  @param {DOMElement} node the dom node that is displaying the command, or a node in the parameter collector area
  @param {Function} fillFunction a function that will fill the parameter area
  @param {Function} onClose a function that will be called when the user closes the collector
  @param {String} name the label that will be used for the dialog title
