Applied modified patches from Jim Smith (jgsmith@tamu.edu) to
do the following:Allow you to read in the XML/Perl configuration file from
somewhere else and pass it to Workflow::Config as a scalar
reference.You can subclass Workflow::Factory and still use 'FACTORY' to
import the factory of the class you want and 'instance()' to do
the same.Added docs for these new features, and added tests for at
least the factory subclassing feature.
