Document API arguments

[GoogleCodeExporter]

I've just been confused by the API sexp_string_ref procedure. I'd assumed it 
would take a Scheme string and a C integer as an argument, and return a C 
integer. Nope. I had to grep the source code to figure out that it takes a 
Scheme string and a Scheme fixnum and returns a Scheme character (which is a 
pretty odd way of accessing bytes in UTF-8 string). Can you document the 
argument types for this and other similar functions? Thanks.

I've addressed this for strings, but will leave the bug open and review
other sections before making a release.
