Breadcrumb navigation

[lamby]

Overview

A "breadcrumb trail" is a type of secondary navigation scheme that reveals the user's location in a website or Web application. For example, "Open image -> Detect and select -> ...". We should add this for mnavigation based on the current stage in the analysis to aid the end-user

Expected Behavior

The current page should be highlighted:

The links do not need to be actual hyperlinks, merely text.

Technical details

We should avoid DRY (Don't Repeat Yourself) violations by duplicating the HTML on every possible page with slightly different markup. The links do not need to be clickable.
