Refactor info

[pataei]

• info is renamed to tags when passed. the info module is still named info.
• tags is a record's field across all data types.
• it is also polymorphic. so pblah is the polymorphic type and blah then instantiates it with Info.
• make ci-test is added to the build CI.
• the runtime values ignore the tags. when we have the time it'd be preferable to refactor them so that the tags aren't being passed to them.
