Order elements according to the order provided by the include statements.
If no includes has been configured, return the given list unaltered.
Otherwise arrange the elements from the list in to the include order and return a new
list.

If an include specifies an element which does not exist, an exception is thrown.

@param namedList the list to order
@param type a description used in an error message (like 'generator' or 'enricher')
@param <T> the concrete type
@return the ordered list according to the algorithm described above
@throws IllegalArgumentException if the includes reference an non existing element
