Added FizzBuzz example

Added a fizzbuzz solution to the examples folder. I tried to use
a range of the different features within LFE/Erlang so it wasn't
a plane and boring example. There is pattern matching, guards,
higher order functions, and tail recursion(?).

The recursive attempt (fizzbuzz:buzz2/1) gives some interesting
results when printing in the repl. The results seem to be correct
in that the individual results are correct. But displaying them
seems to be pretty entertaining.
Updated copyright & licence info

Updated my file to be consistent with Robert's other example by
including the licence and copyright information as well as the
description and author info in the same format.
Updated Recursive Implementations.

Updated the two recursive implementations to demonstrate different
ways of handling recursion. As well as different ways of dealing with
the use of the cons function.

Improved the description of the error handling in the first buzz function.
Updated Pattern Matching Braces to ```[]```

The penny dropped, updated my pattern matching to square braces as
per rvirding's suggestion.
