All casts in the instrument specific classes have been removed. No rework has been done on the GInstDir interface. Not clear whether we really need a rework, as long as we don’t have the need for a cast.

I did not manage to circumvent casting :(

Here’s what I added for the moment to the GCTAInstDir class:

%extend GCTAInstDir {
    GCTAInstDir(GInstDir* dir) {
        GCTAInstDir* ptr = dynamic_cast<GCTAInstDir*>(dir);
        if (ptr != NULL) {
            return (ptr->clone());
        }
        else {
            throw GException::bad_type("GCTAInstDir(GInstDir*)",
                                       "GInstDir not of type GCTAInstDir");
        }
    }
};

The only advantage with respect to the former implementation is that it is nicer ...
