Circa-Date: CRUD Work
Timelines and exhibits' circa date choices are now loaded and settable in their respective edit panes, and are stored in the database. They are also maintained in the virtual canvas. Remaining work would be to change how timeline blocks and exhibit circles render in the canvas to indicate that a date is approximate.

Circa-Date: Exhibit Rendering

Exhibits now render with dotted border if their dates are approximate.
Note that this only works in browsers that support the proposed HTML5
setLineDash canvas method. Tested OK in IE11, latest Chrome and latest
FireFox. Failed in most recent Windows Safari, which is no longer
maintained. Should work on latest Mac Safari.
Circa-Date: Timeline Rendering

Timelines now have dotted line borders on left or right side if the
appropriate circa date checkboxes are marked. (Refresh may be required.)
Page Template Clean-Up

Removed hard-coded reference to ACL script on
cz-nodelete-chronozoom-test.accesscontrol.windows.net.

Placed CZ JS bootstrap inside a jQuery document ready to help ensure
prerequisite JS scripts are already loaded before CZ JS scripts consume
them. This will likely help with some of the undefined errors being
logged.
