~~~~~~~~~~~~~~~~~~~~~~~~

Extract top level Flows as Lambda functions matching datatype in flows.

Lambda functions will change its type to reflect the choosen datatype
as long as it is a non-generic function type and can be matched against
connected nodes. Datatypes configured that fail to satisfy the above
are simply be ignored.

*Input ports*:
    :Filenames: [datasource]

        Flow filenames containing Lambdas

*Output ports*:
    :Functions: [() -> ()]

        Lambda functions

*Configuration*:
    **Datatype** (datatype)
        Non-generic datatype to match against lambda functions  in input
    **Strategy for handling extraction issues** (fail_strategy)
        How should the node handle the situation when the extract fails?
