By default the Category is the fully qualified class name of the method being timed. This is then added to the BaseCategory Property (Gibraltar.Agent.PostSharp.GAspectBase) along with "Method Profiling" to form the full category name.
By setting the Category property explicitly you can put a specific timer into a subcategory underneath "Method Profiling".
