Revision 226454

Summary:
Adding an alpha implementation of an SCXML (State Chart XML) engine and an alpha version of a SCXML dialog management strategy for the RDC group container. 

Details:
1) SCXML Engine - The W3C Voice Browser Working Group recently announced the publication of the first Working Draft of State Chart XML. SCXML provides a generic state-machine based execution environment based on CCXML and Harel State Tables. The SCXML Working Draft is available here [ http://www.w3.org/TR/2005/WD-scxml-20050705/ ]. The RDC tag library has included an alpha of a SCXML engine implementation.

The SCXML engine implementation is under development. The major items that are yet unimplemented are: 
a) Multiple (simultaneous) targets for a single transition (Section 3.3.1) 
b) Outgoing transitions from a parallel (Section 3.4) 
c) JOIN (Section 4.3) 
d) SYNCH (Section 4.4)

2) SCXML Dialog Management Strategy - An alpha version of a dialog management strategy for the RDC group container that works off of a SCXML configuration document is provided. A simple example in rdc-examples.war is scxml-dialog-test.jsp
