// Tim McAdoo - 6/9/2000
// This is support for field validation that can change on the fly
// 07/13/2000 - McAdoo - Added support for required fields and new field types
// 07/14/2000 - McAdoo - Added example code & other notes
// 10/06/2000 - McAdoo - updated code to use a switch->case statement; added "number" type
// 03/13/2001 - McAdoo - default date length

// Sample use within a global JavaScript allocation space :
//
//  var currentList = new Array (5);
//  currentList [0] = new rFields ("Name", "Please provide a valid name", "text", 5);
//  currentList [1] = new rFields ("Phone", "Please provide a valid phone number", "Phone");
//  currentList [2] = new rFields ("Email", "Please provide a valid e-mail address", "email");
//  currentList [3] = new rFields ("City", "Please provide a valid city");
//  currentList [4] = new rFields ("Date", "Please provide a valid date", "date", 7, false);
//
//
// This creates 5 validation fields using various optional parameters:
//   0 - Name - plain text, min length of 5
//   1 - Phone - phone formatting (note case insensitive)
//   2 - Email - Email address formatting
//   3 - City - plain text
//   4 - Date - date formatting, min length (not really used in this case), not manditory
//
// Field Types
//   * phone
//   * email
//   * date
//   * number
//   * text
