Section for default values

[Olivercomputing]

In a recent discussion with Jim Northey and Don Mendelson, the topic of default values (e.g. for the 'presence' attribute) came up. It was agreed that, rather than having these values be simply by external convention, that they should be explicitly specified once in a new section in the Orchestra file.

The issue of "default defaults", or globally default values which are determined to be most logical by the FPL community, can be handled by providing them in an initial template for new Orchestra files, which should be made available in any case for de novo development.

Use cases would be helpful for defining requirements.
