Javadoc

[jean-gui]

Till now, documenting the code has not been a priority, but this is probably a mistake. From now on, each time someone writes a new piece of code, he should add the corresponding Javadoc. The same rule should apply to existing code, when you use a function, class, ..., which is not documented, document it. Another good way of documenting existing code is to do this when trying to understand what it does
