Register pipe definitions

The pipe definitions are a collection of items describing the type members used by the mappings. They are used in the UI for changing the default mappings.

1. Create the pipe definitions
   You create default pipe definitions from the built-in Content pipe. You can also create custom pipe definitions.
2. Register the pipe definitions
   After you create the pipe definitions, you must register them.
3. Modify the pipe definitions
   You can modify the definitions of a built-in pipe or custom pipe.
   To modify the pipe definitions you use the GetPipeDefinitions method.

   The method GetPipeDefinitions accepts the name of the pipe as a parameter. It returns a copy of the registered definitions. After your modifications, you must register them again to apply the changes.
