> FunctionQuery can return a score based on a field's value or on it's ordinal value.
> FunctionFactory subclasses define the details of the function.  There is currently a
LinearFloatFunction (a line specified by slope and intercept).
> Field values are typically obtained from FieldValueSourceFactory.  Implementations include
FloatFieldSource, IntFieldSource, and OrdFieldSource.
