#9 Documention: "How to write a responder"

[Keith Flanagan]

Needs updating / rewriting. Needs to cover:
* Maven project directory structure
* Core Microbase service factory meta-project dependency (so your responder can contact to services it requires)
* XFire service magic configuration file - just need to ensure that it exists, and to change the implementationClass line. You don't need to know what this file does in most cases.
* How to implement AbstractResponder
* Talk about topic names for incoming messages
* How to write the constructor for a responder implementation
* Dealing with incoming messages
* How to send outgoing messages

Compute job implementation:
* Maven project setup, dependencies
* How to implement AbstractJob
* Inputs / Outputs
* Doing work - in java
* Doing work - shelling out to command line (how to obtain the platform-specific binary)

Compute job resources:
* Contents of the "mb-resources" directory - i.e., resource files and properties files tagging these resources.
* Packaging requirements for platform-specific binaries

Finally:
* How to schedule jobs from a responder
