Iterator::File::State::Interface -- Interface for Iterator::File state classes
All data sources should subclass Iterator::File::State::Interface, overriding methods as appropriate.
Iterator::File::State::Interface inherits from Iterator::File::Utility.
Each subclass can take a %config hash. Keys/meaning will be specific to each subclass.
Initilizes any requirements for class. (E.g., prepping temp files.) The iterator is not available until after initialize is invoked.
Increments the marker by one.
Return the current value of the marker.
Sets the value of the marker to $num. Note this update is independent of any changes to the source file.
Perform any required clean up once we're done.
