45a6c5a0b6 330 WIP - implements the new data-directed symbol timing and phase
error calculator.  After increasing the gain for symbol timing, this
new symbol evaluator class seems to track the signal very accurately
despite lots of noise and ISI.

b563f2d11b 330 WIP - created new symbol evaluator class that combines phase and
timing error calculation with symbol decision.  In the process of
changing over to this new class and remove the previous implementations
for the 3 values.  This commit includes the partial implementation
so I can access from another dev machine.

148ddd0bd5 330 WIP - P25 C4FM decoder fully functional using DQPSK decoder and
new symbol timing error detector.  Each component now has a subclass
that supports instrumentation for use with the DemodulatorViewerFX
application.

eaf7c7d11e 330 WIP on redesigning the P25 C4FM decoder. Creates a new decoder
based on the P25 LSM decoder using a costas loop and a gardner detector.
Updates the Demodulator Viewer FX application to add in a symbol chart
and a phase error chart.  The decoder won't lock on yet ... still a wip.

030fc1617c 328 Channel Auto-Start capability. Adds auto-start and auto-start
ordering to each channel configuration to provide the user with greater
control over initial application startup configuration.

Adds new dialog window that displays on startup that allows the user to
invoke/cancel auto-start, or simply allow the timer to expire whereby
the channels will be auto-started.

Updates channel table model to include an auto-start column and relabels
the 'Enabled' column to read 'Playing'.

Updates channel editor to change the 'Enable/Disable' button to read
'Start/Stop'.

Changes the 'enabled' property of the channel configuration to indicate
the current 'processing' status - isProcessing().

Channel's XML configuration re-purposes the 'enabled' property to indicate
auto-start and adds a new (optional) auto-start 'order' attribute.

c2fcc9e85d 321 - adds a preferred tuner option to the channel's source configuration
so that on startup, the application attempts to source the channel from
the preferred tuner.

If the tuner is currently not available, or if the tuner cannot source
the channel, then the next available tuner is selected.

processor.

188a521770 Adds wave file ID3 metadata chunk to audio recordings.
Updates wave writer to add the metadata LIST and ID3 chunks to the end
of the recording so that the file contains the final/complete set of
metadata that was accumulated over the call lifecycle.

6e352143d2 Adds wave file LIST metadata chunk to audio recordings.
Note: the metadata chunk may be added multiple times over the life span
of an audio call, as additional metadata details are added.
