Detailed Description

A future functor object provides a callback interface for applications that wants to serialize data for a future only when it is absolutely necessary. Tasks can return a pointer to an object that implements the future functor interface. Legion will then perform callbacks if/when it becomes necessary to serialize the future data. If serialization is necessary then Legion will perform two callbacks: first to get the future size and then a second one with a buffer of that size in which to pack the data. Finally, when the future is reclaimed, then Legion will perform a callback to release the future functor from its duties.
