//This file containe 3 simple javascript functions that may become usefull.   //
//     The first one, MoneyFormat, will take a str, and turn it into a        //
//properaly listed dollar amount. It will make sure the number has 2 decimals //
//and digit grouping, thousand marker.                                        //
//                                                                            //
//     The second one, isNum, is used by the MoneyFormat to determine if the  //
//string only has numeric digits.                                             //
//                                                                            //
//     The second one, screenpop, is used to popup a window.                  //
//                                                                            //
