MEOW_Field :: count()
Returns:
This method’s behaviour depends on the type of field you’re dealing with. If the type delegate of this field (that is, the class that represents the field type) provides a count method, this method will return the result of that. Otherwise, this simply returns 0 if this field is empty, or 1 if it is not. Since MEOW_Field extends WOOF_Collection which implements the countable interface, you may also call count directly on this field object to check the count (see example)
