use proper attribute name for UDH score.
use newer library versions in requirements.txt
Do not make table editable if a score object already exists.
Introduces a new issue: when score is updated, new values are not
displayed properly.
fix previously introduced bug and introduce common base class
(ScaleBaseModel) for scales (UDH/UXC)
use cached collection when uploading trails.
trails are created via the collection, so that user sees newly created
trail without page refresh.
Use actual values for chart. currently only works for UDH scores. UXC
requires percentage values as points are unevenly distributed among
fields.
add max points info to draw score charts for UXC ratings with proper
scaling.
use Mixin for form error handling.
needs further changes.
fix: reference view attribute that holds elements name.
