GCP Issue 6 - Improve code quality

[cverges]

Reported by legege, Nov 18, 2009
A basic list of things to do that would help to improve the quality of this
library:

• Meaningful JavaDoc
• Standard: code formating, avoid _ in method names, ...
• Remove dead code and code that is no longer used (comments)
• Package name: com.googlecode.expect4j
• Avoid public/package attributes
• Avoid utils class (ExpectUtils)

I've refactored this library to remove the dependency on the tcl library. Of course, this removes the Expect
script tcl execution feature.

I've also completed basic code quality improvements. There are still a lot to do (e.g. break down the expect
method in Expect4J.. this method is unreadable). Unit tests are not deterministic (sometimes fails), exactly like
the HEAD version.

If the community is interested, I can commit this into a branch.
