InputColumn methods could be properties

[ADBond]

Lots of InputColumn methods (name, name_l, l_name_as_l, ...) could be properties instead, and I think that would make the usage of the class a little nicer.

Some of them may indeed make more sense to remain as methods, and there may be some reasons why things are as they are.

Yes, I agree. I think it's because when they were first written they had an argument.

I removed the argument, at which point they should have been made properties, but I didn't think of it
