+ExampleDataPilotSource
+======================
+
+This example shows how you can implement an external DataPilot
+component.
+
+Simple usage scenario:
+======================
+1. build and deploy the component
+2. open a new spreadsheet document
+3. select for example cell B:2
+4. start the DataPilot dialog
+   Data->DataPilot->Start...
+5. select "External source/interface -> Ok
+6. select the example DataPilot
+   Use the drop down list and select the service
+   "ExampleDataPilotSource" -> Ok
+7. Place some number fields in the field areas
+   For example:
+   - select the "ones" field and drop it in the "Row Fields" area
+   - repeat this step with the "tens" and "hundreds" field
+   - select the "thousands" field and drop it in the "Column Fields"
+     area.
+   -> press Ok
+8. you see a matrix with rows and columns for the selected fields
+   and a value area with a sum up of all fields valid for this
+   coordinate. For example cell F:21=1221 (ones=B:21=1, tens=c:21=2
+   hundreds=D:21=2 and thousands=F:3=1)
+
