Detailed Description

This class builds the send_list of old dof indices whose coefficients are needed to perform a projection. This may be executed in parallel on multiple threads. The end result is a send_list vector which is unsorted and may contain duplicate elements. The unique() method can be used to sort and create a unique list.
