Teuchos: more complete and consistent YAML support
Created by: ibaned
This enhancement supports gahansen/Albany#74. Albany uses TwoDArray type ParameterLists, and getting these supported in the YAML parser would streamline our migration from XML to YAML. There should be no compatibility issue, as I don't think the current parser can handle nested Sequences. A unit test is included.

This builds on #1111, please resolve that one first.
