Append

This component accepts data from it's inbox "inbox" and appends the data to the end of the given file.

It takes four arguments, with these default values:

filename = None
forwarder = True
blat_file = False
hold_open = True

filename should be clear. If you don't supply this, it'll break.

forwarder - this component defaults to passing on a copy of the data it's appending to the file. This makes this component useful for dropping in between other components for logging/debugging what's going on.

blat_file - if this is true, the file is zapped before we start appending data.

hold_open - This determines if the file is closed between instances of data arriving.
