A sink that uses a Groovy script for processing the token(s).

Input/output:
- accepts:
adams.flow.core.Unknown


Valid options are:

-D (property: debug)
    If set to true, scheme may output additional info to the console.

    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
