Hi Myron,
you can find it in the WebRatio Explorer View. In this specific case you can see the sample project "GoogleMapUnitSample" in "Web Projects" folder and the component project in "StoreComponents" folder.
If you want to add it to your Web project you should edit the Dependecies section (in the "Project" tab) in order to add the reference to this component. This component is available in the "StoreComponents" of the "components" toolbar.
