clickable navigation

[JanniRoebbecke]

Description

fixes #316

• the user can now click on past steps in the sidebar in order to navigate to these steps

Changes

• in sidebar_section.html, for all past steps the section name text field was replaced with a button, triggering the navigate method in view.py
• in view.py the navigate method was added to manage one of the added buttons beeing clicked
• in run.py the navigate method was added to navigate to a past step
• in workflow_helper.py the method get_global_index_of_step was added. This is used by the navigate method to determine if the given step is a past step determining whether we can navigate to this step

Testing

• step through the workflow to any step, except the first one
• in the side bar click on the name of one of the past steps
• the run should continue at the step you have clicked (just like when you would have clicked back repeatedly)
