ford.graphs.BadType: "Unrecognised object type 'str' for object 'bias_corr' when constructing graphs"

Ford is awesome 🎉 Thanks for building and maintaining this.

I'm creating FORD docs for a rather large and complex code base. The docs build fine when graph: false, but when graph: true I run into the following error.

ford.graphs.BadType: "Unrecognised object type 'str' for object 'bias_corr' when constructing graphs"

I think this error means the module it is trying to make a graph for does not exists as far as FORD is concerned (how/where that module is linked during compile is still a mystery to me).

Perhaps with this kind of error FORD could throw a warning instead and skip making a graph for items like this.

For now, I bypassed the error by excluding the files and dirs that use that module.

Thanks for your consideration.

Thanks for the bug report @blaylockbk! If you're able, please could you see if #494 fixes things for you? If not, if you can point me at your project's source, I can try myself.

Thanks for the quick fix! This solved the error for me.
