Use singleton for Parameter

[GoogleCodeExporter]

com.truemesh.squiggle.Parameter should have a method getInstance() that would 
always return the same Parameter instance, so that we don't have to create a 
new one everytime we use it.

Since parameter is stateless, there won't be a problem in sharing the instance.

Attached is the simple path to Parameter.java to achieve this.
