/*************************
FILE: Validate_Functions.js

DESCRIPTION: This file contains a library of validation functions
  using javascript regular expressions.  Library also contains functions that re-
  format fields for display or for storage.
  

  VALIDATION FUNCTIONS:
  
  stringFilter - Strips out designated characters
  validateEmail - checks format of email address
  validateUSPhone - checks format of US phone number
  formatPhone - place this in the onblur event of <INPUT
  validateNumeric - checks for valid numeric value
  validateInteger - checks for valid integer value
  validateNotEmpty - checks for blank form field
  validateUSZip - checks for valid US zip code
  formatdate - place this in the onblur event of <INPUT
  validateValue - checks a string against supplied pattern
  formatdate(field) - formats for a valid date entry
  doDateCheck(from, to) - makes sure that from is less than to date
  validateField(field) - checks the value entered into an <INPUT for chars or numbers only
  validateAlphaField(field) - only allows alpha chars (place in onBlur event of Input)
  validateNumericField(field) - only allows numeric chars (place in onBlur event of Input)
  
  FORMAT FUNCTIONS:
  
  rightTrim - removes trailing spaces from a string
  leftTrim - removes leading spaces from a string
  trimAll - removes leading and trailing spaces from a string
  removeCurrency - removes currency formatting characters (), $ 
  addCurrency - inserts currency formatting characters
  removeCommas - removes comma separators from a number
  addCommas - adds comma separators to a number
  removeCharacters - removes characters from a string that match passed pattern

 SpryMenuBar.js
 This file handles the JavaScript for Spry Menu Bar.  You should have no need
 to edit this file.  Some highlights of the MenuBar object is that timers are
 used to keep submenus from showing up until the user has hovered over the parent
 menu item for some time, as well as a timer for when they leave a submenu to keep
 showing that submenu until the timer fires.
