Yes! Documentation, especially of the internal parts, can definitely be 
improved a lot.
What is also a bit annoying at the moment is the amount of warnings 
Doxygen generates. Some of them are valid and shall be fixed, some are 
because our inheritance is too complex for Doxygen and should be 
worked-around (we already have som #ifdef EIGEN_PARSED_BY_DOXYGEN hacks 
inside the code). If you are into preprocessor-hacking, you may also 
have a look at Bugs 833 and 402 to reduce the amount of boiler-plate code.

But, as said before, start with what you feel most comfortable with or 
what you are most interested in. And don't hesitate to ask, if you have 
trouble understanding something.
