widgets can be placed into a new window just by calling show().

- #406: Applying alpha mask on numpy.nan data values
- #566: ArrowItem's `angle` option now rotates the arrow without affecting its coordinate system.
The result is visually the same, but children of ArrowItem are no longer rotated
(this allows screen-aligned text to be attached more easily).
To mimic the old behavior, use ArrowItem.rotate() instead of the `angle` argument.

scientific notation (%g). This can be overridden by providing `format={value:g}` when
creating the parameter.

- #410: SpinBox siPrefix without suffix is not longer allowed, select only numerical portion of text on focus-in
allows functions defined in the console to access the global namespace.

- Workaround for PySide bug; GradientEditor fixed
- Prefer initially selecting PlotItem rather then ViewBox when exporting
- Fixed python3 import error with flowcharts
Cleaned up examples, made code editable from example loader
Minor documentation updates
Features:
- Added GraphItem class for displaying networks/trees
- Added ColorMap class for mapping linear gradients and generating lookup
tables
(Provides gradient editor functionality without the GUI)
- Added ColorMapWidget for complex user-defined color mapping
- Added ScatterPlotWidget for exploring relationships in multi-column
tables
- Added ErrorBarItem
- SVG and image exporters can now copy to clipboard
- PlotItem gets new methods: addLine, setLabels, and listDataItems
- AxisItem gets setTickFont method
- Added functions.arrayToQPath, shared between GraphItem and PlotCurveItem
- Added gradient editors to parametertree
- Expanded documentation, added beginning of Qt crash course
Bugfixes:
- Fixed auto-ranging bugs: ViewBox now properly handles pixel-padding
around data items
- ViewBox ignores bounds of zoom-rect when auto ranging
- Fixed AxisItem artifacts
- Fixed GraphicsItem.pixelVector caching bugs and simplified workaround for
fp-precision errors
- LinearRegionItem.hoverEvent obeys 'movable' flag
- Fixed PlotDataItem nan masking bugs
- Workaround for segmentation fault in QPainter.drawPixmapFragments
- multiprocess and RemoteGraphicsView work correctly in Windows.
- Expanded python 3 support
- Silenced weave errors by default
- Fixed " 'win' in sys.platform " occurrences matching 'darwin' (duh)
- Workaround for change in QImage API (PyQt 4.9.6)
- Fixed axis ordering bug in GLScatterPlotItem

Plotting performance improvements:
- AxisItem shows fewer tick levels in some cases.
- Lots of boundingRect and dataBounds caching
(improves ViewBox auto-range performance, especially with multiple plots)
- GraphicsScene avoids testing for hover intersections with non-hoverable
items
(much less slowdown when moving mouse over plots)
Improved performance for remote plotting:
- reduced cost of transferring arrays between processes (pickle is too
slow)
- avoid unnecessary synchronous calls
Added RemoteSpeedTest example

Documentation:
- Added documentation on export system
- Added flowchart documentation and custom node example
Bugfixes:
- prevent PlotCurveItem drawing shadow when unnecessary
- deprecated flowchart.Node.__getattr__ -- causes too many problems.
