Setup development branch dev
created some most basic models

namely, blood_oxygen_reading, patient, physician
Generated PatientController with actions for all tabs, added empty methods to BloodOxygenReading
Generated ThresholdValues model, wrote initial code for BloodOxygenReading.last_week()
added partials and highcharts javascript for blood oxygen chart
Add columns to blood oxygen readings and threshold values. Add file to mock up data for the database
PatientController#metrics now calls BloodOxygenReading.last_week
organized blood_oxygen.js into the proper asset directory
Merge branch 'patientController' into dev
Linked together JS and Rails. Need to figure out how to pass Rails variable to JS file
Threshold and Data fetched from Blood-Oxygen-Reading and displaying in HTML. Further massaging needed to get data into JS, but the javascript_tag appears to be functional
Got end-to-end data from model to JS chart
Cleaner implementation - only passing one values array to the JS chart instead of two. Less code. More readable. Such commit
