Commenting out some CISM-Albany optimizations I made on Oct. 30 that were
causing code to stall on some large-scale CISM-Albany runs on large #s of cores.

The changes amount to reverting these commits to the then-master, now-epetra branch:

e7cb2adb29aa0e991150b744a8ca9d7f1a8dd48e
571403f2431b3244186930270c07a6532e6cc43c

The 2nd one was the problematic one.

Also turning off lateral BCs for now as they require more testing for general problems.
