Need metadata to define the type of analysis being performed

[ASL-rmarshall]

Although it is possible to categorize analyses (and outputs), there are no standard categorizations that can be reliably interpreted to drive automation of input table processing. It might be better to have defined metadata attribute(s) on the Analysis class to indicate what type of analysis is being performed, e.g.:

• Within-dataset summary
• Within-dataset comparison
• Subject incidence (i.e., whether events occurred for subjects in particular groups)
• Etc.
