Introduction

The code below describe a set of interfaces and helper classes for creating addin tools. Essentially, these interfaces are used to encapsulate algorithms (or anything that returns point locations given a UV paramters) so that they can be used by other applications.

Essentially, there are two main concepts, an Algorithm that in this case is a simple function called getXYZ() and parameters which can be set to get variations on the algorithm's output. The remaining methods and properties simply return information about the algorithm, parameters, and the addin tool. This includes names of parameters, descriptions, and an image to represent the "addin" tool.

Note that generics are used for parameters. The existing Math Sculptor application makes use of input parameters of bool, int, and double. However, there is no reason why other types can not be used.
