* Move some things around to facilitate plundering libraries for other
  applications without needing to duplicate so much code.
    sv/osc -> data/osc
    sv/audioio -> audioio
    sv/transform -> plugin/transform
    sv/document -> document (will rename to framework in next commit)

-/**
- * A Sonic Visualiser document consists of a set of data models, and
- * also the visualisation layers used to display them.  Changes to the
- * layers and their layout need to be stored and managed in much the
- * same way as changes to the underlying data.
- * 
- * The document manages:
- * 
- *  - A main data Model, which provides the underlying sample rate and
- * such like.  This must be a WaveFileModel.
- * 
- *  - Any number of imported Model objects, which contain data without any
- * requirement to remember where the data came from or how to
- * regenerate it.
- * 
- *  - Any number of Model objects that were generated by a Transform
- * such as FeatureExtractionPluginTransform.  For these, we also
- * record the source model and the name of the transform used to
- * generate the model so that we can regenerate it (potentially
- * from a different source) on demand.
- *

-# A very simple command shell for Sonic Visualiser.
-# 
-# This provides a wrapper for the sv-osc-send program, which is a
-# generic OSC sending program (not specific to SV, despite its name).
-# This script attempts to guess the OSC port number for an SV
-# process running on the local host, and then composes a method name
-# and arguments into a complete OSC call.
-# 
-# You can either run this with the method and its arguments on the
-# command line, e.g. "sv-command set layer Frequency-Scale Log", or
-# you can provide a series of method + argument commands on stdin.
-# 
-# Unless you use the -q option, this script will echo the OSC URL
-# and arguments that it is sending for each command.
-#
-# Note that the method and arguments may not contain spaces.
