Very nice library.

I have some code which is base64-encoding limited so this interests me
particularly. Currently I use OpenSSL's implementation which I found to
be the fastest in my case. So I ran a small benchmark against your
library and it performed really well, though a bit slower. I manage to
get 566.074 Mb/s with OpenSSL versus 517.928 Mb/s with stlencoder. The
benchmark simply consists of loading a large file (~200 Mb) in memory
and encoding it in a pre-allocated buffer. I've attached the source.
Please tell me if you see anything wrong with it. I use g++ 4.7.1 with -03.
