## Standardize Case of List Items

This function's purpose is to standardize the alphabetic case of items in fields which are associated with Preference lists. If a field contains multiple items separated by the Multi Value Delimiter, each value will be processed individually. If a specified field is not associated with a list, nothing will be modified.

Each value in a field will be compared against a possible value in its associated list. If the item is found to be in the list with a different alphabetic case than the current value, the current value will be changed.
