One of the main feature that the SWH web user interface will have to offer is the easy browsing of a source code tree (like any software forge web interface). As a first task for the beginning of the development of the swh web browse ui, let's implement it.
The associated sub-tasks are the following:
[x] add basic views for browsing directories and content objects from their sha1_git checksums
[x] add views for browsing those objects from a specific origin and its visit by swh.
[ ] enrich those views with person metadata and last history log
[x] add view for browsing the history log of a specific revision
[x] add a simple interface to search software origins to browse based on their urls
