//
// Progress Bar
//
// This is a javascript that simulates a progress bar on the page.
// The progress is based on the return value of an external functional call
//
// Usage: showProgressBar(ec,tbpFunction,doneFunction,divObj,
//                        timeInterval,message1, message2,
//                        color,height,width,style)
//   ecVarName    - ECommerceInterface object variable name string
//   tbpFunction  - returns progess text and bar %.  see updateProgress()
//                   (tbp stands for text and bar per cent)
//   doneFunction - javascript function to call upon completion
//   divObj       - id of the div object that act as a container of this progress bar
//   timeInterval - time interval (milliseconds) to obtain the status and update the progress bar
//   message1     - a msg string to display before the progress %
//   message2     - a msg string to display after  the progress %
//   color        - color for the bar/outer boundary of the box 
//   height       - height of the box/bar
//   width        - total width of the box/bar 
//   style        - style for the message string displayed above the progress bar
//
// Requirements: Following code must be included in the page
//
//     var ec = new ECommerceObj;  // global variable
//
//     <DIV id="divObj"></DIV>
//
// Where the name used for ec and divObj are passed as args to showProgressBar.
