Code for running a tool, model, or script from within an Arc AddIn

Details

This code runs a tool from an Arc addIn. It assumes the Tool is in a Toolbox loaded into ArcToolbox. The example given takes in four parameters (a layer, a feature dataset, a distance, and an output layer). In the absence of the latter, models generally output to the default geodatabase in "My Documents/ArcGIS/AddIns/" (provided you have permission -- otherwise they'll just fail). If the output directory is where your map data is, the final layer will generally load as a layer as well as being produced.

This code differs from the original code in running inside Arc. You do not need to generate wrappers using the Eclipse ArcGIS Menu -> GeoProcessing Tool Code Generator, for tools loaded into Arc.
