Support multiple episodes of care (EoC) for continuous variable (CV) measures

#### Story ####
- https://www.pivotaltracker.com/story/show/65923976

#### Notes ####
- <code>OBSERV</code> values are now stored as an array of values (minutes or percentages), and <code>result</code> values are properly read when comparing expectations against results
- the values for <code>OBSERV</code> and <code>result</code> are sorted before comparison
- the number of <code>OBSERV</code> values one can enter in the expected values section is dependent on the value entered for <code>MSRPOPL</code>, which updates the inputs via a <code>blur</code> event
- <code>rake bonnie:db:reset</code> and <code>rake bonnie:test:clean_up</code> were updated for expedited testing
- proposed testing strategy
  - <code>rake bonnie:db:reset DB=bonnie-production-eh</code>
  - <code>rake bonnie:test:clean_up</code>
  - login with <code>bonnie@example.com:bonnie</code>
  - create a test patient for <code>CMS55v2</code> that produces >= 1 <code>MSRPOPL</code> and >= 1 <code>OBSERV</code> results

- updated expected values section provides multiple <code>OBSERV</code> inputs, with no order necessary
