Composit widget to allow user to enter e.g. height / weight values and convert between units. See jQuery.ui.unitconverter.Example.html for a working example for height/weight inputs.
Major overhaul. Slider now replaced with a spinner which makes the interface much more compact. maskedInput replaced with the far more flexible autoNumeric. Code completly re-enginered to use better design principles and make maintainence easier. Units specification moved to HTML rather than JavaScirpt making it easier to do things like localise the labels and add them dynamically.
