USAGE GUIDE - Notes
1) All parameters are mandatory.

/*
USAGE GUIDE - Basic Functions
To validate a field
	validate("<Form Name>", "<Field Name>", "<Validation Function>", "<Validation Message>");
	Standard Validation Functions are:-
		basic - text, textarea, hidden, or file : Will validate if the field is not blank.
		      - checkboxes or radios : Will validate if at least one is checked.
		      - select : will validate if the value of the selected option is not blank.
		email - text or textarea fields only. Will validate if a valid email address.
		numeric - text or textarea fields only. Will validate if a number.
		Checkbox - Checkbox ; will check if a single box is checked.
		altered - text, textarea, hidden, or file : Will validate if the value is different to the default value.
		        - select : will validate if the selected option is not a defaultSelected option (does not have SELECTED in the option tag)
	NB. Do not put ()s after the function name.
	You can also write your own validation functions - see Advanced Functions, below.
*/

/*
USAGE GUIDE - Advanced Functions
To change the first line of the error message:-
 -	setBaseError("<Form Name>", "<New Error Message>");
To make the form execute javascript just before it submits:-
 - 	setPreSubmitAction("<Form Name>", "<Script to execute>", <true or false - whether the form submits>);

When writing your own functions, be aware of the input and output to the function.
	Input - The function is passed one parameter : The object of the field to be validated.
	Output - The function must return true if the field is valid, false if not.
