Break out the plugin into three different plugins (using the same class in different modes) in order to provide simplistic and more sophisticated spectrograms as well as the f0-gram. Remove the program support, since it doesn't work usefully anyway (it just overrides the user's preferred settings).

// This is a skeleton file for use in creating your own plugin
// libraries.  Replace MyPlugin and myPlugin throughout with the name
// of your first plugin class, and fill in the gaps as appropriate.
