Description:

the Metabase manpage is a framework for associating content and metadata
with arbitrary resources. A Metabase can be used to store test reports,
reviews, coverage analysis reports, reports on static analysis of coding
style, or anything else for which datatypes are constructed.

Metabase::Fact is a base class for Facts (really opinions or analyses) that
can be sent to or retrieved from a Metabase repository.

Structure of a Fact object
A Fact object associates a 'content' attribute with a 'resource'
attribute and a 'creator' attribute.
