Implemented MPI operations MINLOC and MAXLOC and associated datatypes
for collective routines. Still need to do it for point-to-point, if
they are ever used in that way. Still need to think more deeply
about how to handle structs in general for MPI.
Found additional uses of deprecated $state and deleted them.
Added further complex and collective examples. Still need to make
them into JUnit tests.
