Refactor: readability

Hello Raquel,

I've produced a couple of refactorings for the EclipseWriter. Especially for the readability and the indentation levels :-) 

As there were no tests, I had to refactor without a safety net :). Please feel free to discard these changes 

Cheers,

PS: Maybe you could point me where to continue digging and refactoring or advancing functionality. If there are some tests already in place, even better!
