[OSRS-PROJ] Exported function documentation

[Paul Selormey]

Hello Frans,

> Have been able to compile the whole code without any warnings?

Yes, it went without warning at the VC++ warning level 3 (the default).
Actually, the #include <project.h> caused a lot of warning, but I fixed it
by telling the compiling to use the project directory as additional
"include"
directory and that was all.

The utilities, however, need some extra work.

I need it too :-)

The only thing is to understand the exported functions very well and
then wrap them. The OpenGIS stuff may however involve a little bit
of reading but I will give it a try,

Best regards,
Paul.
