Complete QuVR MD for GTFS RT research and metric requests

[machow]

To go over with @chriscardillo next week, to sanity check the views we are creating. Below is a list of many questions which have been asked of GTFS RT data.

Depencies

These questions all depend on the availability of a built-out RT pipeline which is being tracked in:

• [x] cal-itp/data-infra#221

Issues

• cal-itp/data-analyses#262
• cal-itp/data-analyses#261
• cal-itp/data-analyses#260
• cal-itp/data-infra#205 - (many questions -- I would just write out the views involved for now)
