Changed file mode to be executable.
Modified "jack meter" command to return a proper Tcl list of Tcl double values.
Refactored audio stats to be a struct to support multiple meters.
Now allocates two input audio ports for metering (not yet properly supported by "jack meter").
Multi-port "jack meter" command now working, AFAICT. :)
