I'm getting errors in the examples code that comes with controlP5.  Here are a few examples.  The others work so I think I installed it correctly in the libraries folder.  Version is Processing 1.5.1, controlP5 0.7.2, just ran the examples with no changes.

ControlP5accordion:

line 103:  cp5.mapKey(new ControlKey() {public void keyEvent() {accordion.open(0,1,2);}}, 'o');

Error: The function mapKey(new ControlKey(){}, char) does not exist. 

ControlP5chart:

line 22: ChartDataSet cds = myChart.addDataSet();

Error: The method addDataSet(String) in the type Chart is not applicable for the arguments ()

ControlP5bitFont:

line 23:   label = new Label(this, "some funny text here.", 100,40, color(255));

The constructor Label(ControlP5bitFont, String, int, int, int) is undefined

ControlP5diyController:

line 25:   cp5.register(pad);

The method register(Object, String, ControllerInterface<?>) in the type ControlP5 is not applicable for the arguments (ControlP5diyController.ControlPad)
