/** \class InteriorExteriorSpatialFunction
* \brief Returns whether or not a location is "inside" or "outside" a function
*
* InteriorExteriorSpatialFunction is a specialized version of SpatialFunction
* where the output type is a boolean. In particular, the return type is understood
* to mean the following:
*
* A return of 1 means inside or on the surface of the function,
* 0 means outside the function
*
* There is no implied meaning in the terms "inside" or "outside"; although
* the standard assumption is that "inside" means "bounded by a closed surface",
* alternative definitions are also fine. For example, inside might be one side
* of a plane, outside the other side.
*
* A typical use for an InteriorExteriorSpatialFunction is to generate test
* primitives of arbitrary dimensionality, in conjunction with
* itk::SpatialFunctionImageEvaluatorFilter or itk::FloodFilledSpatialFunctionConditionalIterator
*
