Interface Summary

Interface	Description
Fn<IN,OUT>	Interfaces for functional programming The main interface, Fn, is genericized by an input IN and output OUT.
Fn.AndN<IN,OUT>
Fn.N<IN,OUT>	Optional additional interface if we can take an array / varargs
Fn.Pdouble	"Efficiency interface for dealing with primitive doubles
Fn.Pdouble.AndN
Fn.Pdouble.N	Optional additional interface if we can take an array / varargs
Fn.Pint	"Efficiency interface for dealing with primitive ints
Fn.Pint.AndN
Fn.Pint.N	Optional additional interface if we can take an array / varargs

Class Summary

Class	Description
Fn.Base<IN,OUT>	Base class that throws UnsupportedOperationExceptions for all methods.
Fn.Pdouble.Base	Base class that throws UnsupportedOperationExceptions for all methods.
Fn.Pint.Base	Base class that throws UnsupportedOperationExceptions for all methods.
Fns	A bunch of implementations of basic Fns Mimics Scala's collection : min, max, sum, product Suffixes of "pdouble" or "pint" indicate that they deal with primitives
FP	Static utilities for Functional Programming

Code for using and linking together functions, inspired by javascript/Scala/Groovy. Functions may have an Object version, using Objects as inputs/outputs (generified by IN, OUT) For efficiency, there are specific versions dealing with primitive doubles and ints

Typical usage:

1. Implement Fn (or Fn.Pdouble or Fn.Pint), perhaps by extending one of the Base classes.
2. Check out the Fns class (and FPTest) for examples
3. Combine your Fn with one of the utility methods from FP.

TODO - combine these somehow with Callbacks and CallbackExecutor for multi-threaded processing. Warning: Internally there is no real checking, so if you screw up you'll get a ClassCastException.
