Set the values of multiple custom fields for a given object in a single call.
This is the recommended approach when updating multiple fields on the same object
to avoid race conditions that can occur with concurrent customField.setValue calls.

Note: To set custom fields on an Employee, use user.setCustomFieldValues instead.

The values accepted in the fieldValue param depend on the type of field that's being updated. See the customField.setValue docs for the full per-type table.
