Itasca grid files: binary storage format

Hi there every one!

For some of our 3DEC projects, we rely on meshes that were generated outside of 3DEC.

The merging option works just fine, and thanks a lot for having implemented this!

My question is: is the binary grid file format secret or would it be possible to get the binary formatting logic? Of course, the ASCII does the trick, but being able to write/read as binary would be a plus.

I would totally understand Itasca prefering to keep the binary logic secret!

Thanks for the hint
