Feature time series

[rdoshi99]

Changed get_timeseries, plot_timeseries, and makeplots functions to support the addition of linked brushing and hover tools in the time series plots

• Changed the arguments for the get_timeseries and plot_timeseries functions because the data type to support linking had to be a shared ColumnDataSource and updated the docstrings to reflect the changes
• Added the hover tool in the plot_timeseries function
• Added the tools as an optional argument in the plot_timeseries function
• Linked interactivity includes linked box_zoom, hover, wheel_zoom, and reset

In a followup pull request, I will add the sky brightness time_series plot which is ready to go

The merge conflicts which are left reflect the changes I made to the function calls to plot_timeseries The ones from the featureTimeSeries branch are up to date and should function correctly, so the master copies of the airmass, seeing, exptime, and trasnp figures are outdated

Thanks. I resolved the merge conflict via the github PR web editor, and changed the box_select tool to the box_zoom tool, which matches the PR description. I think zoom will be more useful than select, but we may change our mind after using this for real survey tracking.
