Date Calculation

Implemented date calculation based on the timeframe defined in the
TimeFrameMenu for Nodes and Connections.
Implemented Timeline

Implemented the timeline, which updates the current date and has markers
for each unique date in the system.
TimeObject CurrentDate Implementation

Nodes and Connections now respect the currently selected date on the
timeline. Removed options for how to handle invalid dates.
TimeSeries Node Size and Centrality Coloring

Node size based on number of connections and centrality measures
(including coloring) are now updated when dates are changed.
TimeLine play pause and skip buttons

Implemented skip forward and skip back and added buttons for play and
pause, but didn't implement them.
TimeLine play implementation and misc

Implemented the Play button on the timeline. Also, camera no longer
rotates when clicking a menu, and fixed a bug that was preventing node
resizing when disabling TimeSeries.
