Remove a field without queueing it to be removed from database
Removes a field from the fieldgroup without deleting any associated field data when fieldgroup is saved to the database. This is useful in the API when you want to move a field around within a fieldgroup, like when moving a field to a Fieldset within the Fieldgroup.
$bool = $fieldgroup->softRemove($field);
