Series View

- Created a Series View with controller functions to allow filtering
subjects for list box and to select/de-select units
Added Series view

After adding a unit, user will be directed to series view, where they
see a list of units in the series, and if user is logged in, they can
mark/unmark the current unit in the list as completed or not. Page also
has previous/next buttons.
Series Fixes

- fixed 'mark as completed' button not showing up
- added navigation buttons to first and last units
Added database and tables

- Empty tables (individual with drop table)
- skilljoy.sql tables + data with drop table
Series Fixes

- added link in home view to show series above units
- fixed series view error where controller was trying to retrieve
completion data for anonymous users
- when logged in, home view has option to create series (will later be
changed to accommodate permissions to individually set user permissions)
- moved series controller functions from units to series controller
- home controller also makes call to load series
- trimmed test data from db tables
Attempt to Merge main > series
Fixed Github conflict tag in skilljoy.sql
Modified Unit-Completion feature

- changed unit completion independent of series
- units can be marked as 'complete' in unit view as well as in series
- units marked/unmarked in unit view affects complete/incomplete marker
in series view
Light Series Fix

- Added a friendly line in series to tell user they completed the series
if all the units were completed
Series clarity fix

- units were previously pulled in sequential order but added "order by"
just for clarity
Updated to display link

Shows link if user has permission to add series
Added linking between steps within a series

- navigation buttons at the bottom do not work after clicking one of the
unit title links at the top
