XLLoop is a framework for implementing a warehouse of excel functions
out of process and has the following features:
* Fast binary protocol (overhead approx. one 10th of a
millisecond).
* Extensible server framework.
* Reflection-based function adapter for extremely quick deployment
of java methods.
* Bean scripting framework adapter so functions can be written in
any BSF-supported language.
* Functions can be dynamically added to excel without restart.
XLLoop consists of two main components:
* An excel addin implementation (xll written in c++).
* A server and framework (written in java).
The addin and server communicate via a simple socket-based protocol,
sending and receiving (binary) serialised xl objects (called xlopers).
