Class Summary

Arrays	Non-instantiable class with static utility methods for working with arrays.
AssociatedPolynomial
Constants	Collection of assorted physical constants.
Constants.Alignment	Enumerated type for specifying HORIZONTAL/VERTICAL alignment.
Constants.CompassDirection	Enumerated type for the compass directions NORTH, SOUTH, EAST, WEST.
Constants.Direction	Enumerated type for the directions TOP, BOTTOM, LEFT, RIGHT, FRONT, BACK.
Debug	Class holding static fields that determine whether debugging is on, how much, what types and what (if anything) should be looked at specifically.
DoubleRange
EnumeratedType	EnumeratedType classes are used to define a fixed set of specific values that can be taken by a field.
EventManager	Class to take care of listener lists and event firing for simulation elements.
EventManager.Linker	Class used to construct a two-way linked list of listeners.
FastFourierTransform	This utility receives a set of data points, either Real, Imaginary or Both and performs a Discrete Fourier Transform on them using the Fast Fourier Transform algorithm.
Function.Abs	The function f(x) = abs(x)
Function.Chop	Returns the input value if its magnitude is greater than value specified at construction; otherwise returns zero.

FunctionChain	Defines a function as chain of other functions.
FunctionChain.Link	Class for making linked list of Functions
HistogramCollapsing	Simple Histogram implementation with a static number of bins, but dynamic x range.
