[slf4j-user] SLF4J documentation

[Ceki Gulcu]

Hello all,

With impetus given by Ralph Goers, the SLF4J documentation has been simplified 
and improved. The updated documentation should be especially helpful for new 
SLF4J users. If you find any part of the documentation unclear, please let us know.

TIA,
