Add ability for sequential and parallel task specifications for Workflows
-------------------------------------------------------------------------

                 Key: OODT-70
                 URL: https://issues.apache.org/jira/browse/OODT-70
             Project: OODT
          Issue Type: Improvement
          Components: workflow manager
         Environment: indep. of env.
            Reporter: Chris A. Mattmann
            Assignee: Chris A. Mattmann
             Fix For: 0.2


There has been a lot of internal JPL work on flushing out new ideas with the workflow manager.
One of those new ideas is to explicitly support differentiating between different types of
{code}org.apache.oodt.cas.workflow.WorkflowTask{code} entities, classifying them as *sequential*
(their current form) versus *parallel* (those that deal explcitly with branch and bound).
Even though the current workflow system can support these activities, they are largely code-based
and require modification and intrinsic knowledge of the Workflow event system.

It would be nice to simplify this for the users and allow task.xml, conditions.xml and *.workflow.xml
files (or explicit WorkflowRepos) to support this nomenclature. 

I'll attach a proposed spec of what the updated XML files would look like using this paradigm.
Then my goal is to take the existing workflow system and augment it with this functionality.
