/*
*Following are the functions you can call for form validation
*grep for '- functionname' to jump down to the explanation
*
* - notBlank(obj, fieldname) -
* expects two arguments of object and fieldname
* checks to see if the field is blank
* returns an error if no data is entered into the filed
*
* - isAnyNumber(obj, fieldname) -
* expects two arguments of object and fieldname
* checks that a number has been entered into the field
* returns an error if no number is found
*
* - isNumber(obj, num, fieldname) -
* expects three arguments of object, number of digits required and fieldname
* checks the value is a digit and there are "num" number of digits
* returns an error if it is not a digit with the specified places
*
* - isSelected(obj, fieldname)-
* expects two arguments of object and fieldname
* checks that they have selected any value other than the first one
* returns an error if the first selection is selected
* Special note ---- only use this option if the first value in the drop down is not allowed!!!!
*
* - isExpire(obj, fieldname) -
* expects two arguments of object and fieldname
* checks that the user has entered a date as mm/yy, will automatically replace any "-" with a "/"
* returns error if date is not formatted as mm/yy
*
* - isEmail(obj, fieldname) -
* expects two arguments of object and fieldname
* checks that the user has entered a properly formatted email address in the form of someone@somewhere.somewhere
* Does not check that it is a valid email address, only checks for formatting
* returns an error if the email is not correctly formatted
*
* - numberFormat(obj) -
* expects one argument of the object to format
* replaces any non digits with nothing
* does not error
*
* - phoneFormat(obj) -
* expect one argument of the object to format
* if the length of the field is greater than ten, it deletes any non digit characters and then
* formats the remaining numbers to (...) ...-....
* (could be buggy as I can't see what he does if the remaining numbers are not ten)
* does not error
*
* - isDate(obj, fieldname) -
* expects two arguments of object and fieldname
* replaces any "-" with a "/"
* checks that the remaining value matches the mm/dd/yy format
* returns error if the formatting doesn't match
* (could be improved by checking for a "valid" date, as in the month field being between 01-12 etc)
*
* - id Time(obj, fieldname) -
*  expects two arguments of object and fieldname
* replaces any "-" with a ":"
* replace any non digit characters with nothing
* checks that the remaining value is formatted as hh:mm
* returns error if the formatting doesn't match
*
* - confirmation(msg) -
* expects one argument of the message to populate the confirmation box with
* returns false if they don't agree
