Version: 0.4.2

• Changed how tick labels are rotated to fix strange rounding errors on tick labels and problems
  with tick labels not respecting interactive plot resizing.
• Added a x_slice keyword argument to the plot_tools.plotResListData function. This adds the
  ability to only plot a portion of data. Currently does not check whether all resonators in list
  have the same length data, so be aware of potential for an exception.
