1.2.11 Changes:

* Commenting out tplot_math stuff

1.2.9 Changes:

* Fixed a bug in the pyqtgraph spec plots with time varying bins

1.2.0 Changes:

* Added ability to display an arbitrarily large number of qt plot windows, if done from ipython

1.1.13 Changes:

* Added overplot capabilities to the Qt Plotting routines

1.1.12 Changes:

* Fixed major issue with pip installer

1.1.6 Changes:

* Fixed a spot where python warnings were changed to change back after the function was over

1.1.4 Changes:

* Added a qt option to tplot, which will allow users to just open the HTML file in a browser window

1.1.2 Changes:

* Added support for bokeh 0.12.13

1.1.0 Changes:

* Added the ability to plot directly in the Qt Window with pyqtgraph.  This may entirely replace the bokeh plotting routines at some point.

* Should be able to export to HTML properly now.

1.0.6 Changes:

* Qt is getting rid of support for QtWebView.  QWebEngineView will replace it, but has great difficulty viewing html greater than 2GB.
* As a temporary solution, a local html file is saved, and then read into QWebEngineView.
