* Switched to pyqtgraph for spectrum plot

* Added trigger controls

* Added markers

* Added hotkeys for control

* Added bandwidth control

* Renamed GUI launcher speca-gui

* Created SweepDevice to generalize spectrum analyzer-type function

* Created CaptureDevice to collect single captures and related context

* pyrf.connectors.twisted_async.TwistedConnector now has a
vrt_callback attribute for setting a function to call when
VRT packets are received.

This new callback takes a single parameter: a pyrf.vrt.DataPacket
or pyrf.vrt.ContextPacket instance.

The old method of emulating a synchronous read() interface
from a pyrf.devices.thinkrf.WSA4000 instance is no longer
supported, and will now raise a
pyrf.connectors.twisted_async.TwistedConnectorError exception.

* New methods added to pyrf.devices.thinkrf.WSA4000: abort(),
spp(), ppb(), stream_start(), stream_stop(), stream_status()

* Added support for stream ID context packets and provide a value
for sweep ID context packet not converted to a hex string

* wsa4000gui updated to use vrt callback

* "wsa4000gui -v" enables verbose mode which currently shows SCPI
commands sent and responses received on stdout

* Added examples/stream.py example for testing stream data rate

* Updated examples/twisted_show_i_q.py for new vrt_callback

* Removed pyrf.twisted_util module which implemented old
synchronous read() interface

* Removed now unused pyrf.connectors.twisted_async.VRTTooMuchData
exception

* Removed wsa4000gui-blocking script

* Fix for power spectrum calculation in pyrf.numpy_util

==========

2013-02-01

* API now allows asynchronous use with TwistedConnector

* GUI now uses asynchronous mode, but synchronous version may still
be built as wsa4000gui-blocking

* GUI moved from examples to inside the package at pyrf.gui and built
from the same setup.py

* add Twisted version of show_i_q.py example

* documentation: installation instructions, requirements, py2exe
instructions, user manual and many other changes

* fix support for reading WSA4000 very low frequency range

* pyrf.util.read_data_and_reflevel() was renamed to
read_data_and_context()

* pyrf.util.socketread() was moved to
pyrf.connectors.blocking.socketread()

* added requirements.txt for building dependencies from source
