Back button rework #133
Description
Feature description and context
Now that Scout is being generalized post-KAZA project, we need to allow users to navigate back and forth through the images in a task
Feature sign-off requirements
The changes to the back button should be altered for annotation, review, and ground truth.
- the back button is disabled only on the first image of a task
- the back button is active and available for all other images on a task
Design
on task creation, create an array (or similar structure) that denotes image order. track the position in the array when determining photo to be served
