Format: function ZAPlist($field, $value)
Explanation: This function handles basic list management in ZAP. $value is a CSV list of values.
1) First, the function checks to see if names are being added/dropped (+/-). If it is, it retrieves the corresponding value of $field from the current datapage.
2) Next it works through the CSV array, and one at a time either adds or deletes the specified $fields.
If $value does not begin with a +/-, the entire list is replaced by the contents of $value.
A fairly simple function, but it works well!
