example Vamp plugins and host

Vamp is an audio processing plugin system for plugins that extract descriptive information from audio data - typically referred to as audio analysis plugins or audio feature extraction plugins.

This package contains the following example plugins:

 * Zero Crossings calculates the positions and density of
   zero-crossing points in an audio waveform.

 * Spectral Centroid calculates the centre of gravity of the
   frequency domain representation of each block of audio.

 * Simple Power Spectrum calculates a power spectrum from the input
   audio.  Actually, it doesn't do any work except calculating power
   from a cartesian complex FFT output.  The work of calculating this
   frequency domain output is done for it by the host or host SDK; the
   plugin just needs to declare that it wants frequency domain
   input. This is the simplest of the example plugins.

 * Amplitude Follower is an implementation of SuperCollider's
   amplitude-follower algorithm as a simple Vamp plugin.

 * Simple Percussion Onset Detector: estimates the locations of
   percussive onsets using a simple method described in "Drum Source
   Separation using Percussive Feature Detection and Spectral
   Modulation" by Dan Barry, Derry Fitzgerald, Eugene Coyle and Bob
   Lawlor, ISSC 2005.

 * Simple Fixed Tempo Estimator: calculates a single beats-per-minute
   value which is an estimate of the tempo of a piece of music that is
   assumed to be of fixed tempo, using autocorrelation of a frequency
   domain energy rise metric.  It has several outputs that return
   intermediate results used in the calculation, and may be a useful
   example of a plugin having several outputs with varying feature
   structures.

Also included is a simple host that can enumerate plugins, list their features, and process an audio file.
