#1 Rework of the project

[Brian Wyld]

Changes for next version:
- node graph graphical entry for design of service
- extensible (add new node types that integrate with
rest)
- both basic vxml type nodes and "processing" nodes
- ability to process based on use of document level
vars available between nodes
- for subdialog or submit type accesses, can map vars
only call params/returns
- content (prompts) all based on definition of content
ids
- which are managed by separate program (record,
check, edit, deploy)
- deployed initially as static files only in the published
package
- future can reference a "content server" and get
dynamic content based on selectors...

- basic nodes all generate static vxml
- dynamic elements can be accessed via generic
subdialog node, or specific plugin dynamic nodes which
must also generate subdialog calls
- "dev" project -> has local web server to allow instant
dev/test cycle
- "publish" project -> creates zip of static
vxml+audios+grammars with relative references only so it
can be deployed as a block
