/*
 * GUISETUP.C
 *
 * GUI setup script.
 * Should run before the GUI toolkit is started.
 * It creates the necessary controls for the data generators and the
 * envelope/filter reset mechanism.
 * The script takes the number of channels and sampling frequency
 * parameters (these are necessary to create the controls) from its
 * context.
 * The script has no input or output data.
 * After running once, the script deactivates the node.
 * The node using this script should be created with the highest
 * priority so it runs first.
