Class DataGeneralPathBuilder

java.lang.Object

org.das2.graph.DataGeneralPathBuilder

public class DataGeneralPathBuilder
extends java.lang.Object

introduce class to handle the task of creating GeneralPaths from a series of data points. We notice that creating the GeneralPath is plenty fast, and it's rendering it that is slow, so this will allow for future optimizations.
