Problem: problematic class name in example
Problem: problematic class name in example

I originally wanted to demonstrate how `my class` would get converted to
`my_class` (or `my_class_t`) in the C code bindings. But I'd have to
rename the file as well and even adapt project.xml. I think this feature
becomes straight-forward as soon one gets familiar with GSL.

Solution: Change it back to `myclass`.

The feature is still demonstrated in the `custom pointer` argument at
the bottom where the type `my custom class` is converted to the C type
`my_custom_class_t`.

Just trying to make it easier for developers of new language bindings.
