Brought changes over for broken JSON array (rogue ',' at end of array).
Changes from old (corrupted) repository; added Schaeffer grade for anterior segment. Default is still the original grade, callers need to explicitly call 'grade-schaffer' when setting and getting the parameter.
James' requested changes to NFL defect and disk haemorrhage
Updated optic disk and associated doodles
Fixed gonio tool for values to display.
Fixed issue with incorrect value for gonio grade.
Updated to include changes that stop the optic disk/peripappillary atrophy from writing multiple squiggles to the squiggle array. This is a prelude to getting the toggle function to work for optic disk.
Changes for optic disk to work properly for toggle mode. Added jsonBody in for sublcasses to output their own json in addition to the parent class, optic disk now loads 'isBasic' which needs to be persisted for later use.
