/**
 * ControlP5 properties example (see keyPressed).
 * by andreas schlegel, 2011
 *
 * status: experimental
 * saves/loads controller values into/from a properties-file 
 * by default properties will be saved in a serialized format and use the .ser extension.
 *
 * taken from the changelog;
 * adding saveProperties(String) and loadProperties(String) to 
 * save and load serialized controller properties. 
 * The range of controllers implementing save/load properties currently includes
 * Slider, Knob, Numberbox, Toggle, Checkbox, RadioButton, Textlabel, Matrix,Range, 
 * textarea, ListBox, Dropdown, colorPicker. 
 * Properties are currently saved in the java serialization 
 * format but xml and possibly json alternatives are being worked on.
 *
 *
 * default properties load/save key combinations are 
 * alt+shift+l to load properties
 * alt+shift+s to save properties
 *
