/****************************************************************
FILE: RegExpValidate.js

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


  VALIDATION FUNCTIONS:

  validateEmail - checks format of email address
    validateUSPhone - checks format of US phone number
    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
  validateUSDate - checks for valid date in US format
  validateValue - checks a string against supplied pattern

  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
