Support for class-based model about tsoa

[lukeautry]

I think this should be possible and fairly simple to implement, with the understanding that only class properties would be looked at, not methods.

There's also the slightly more complicated matter of constructor variables, e.g. constructor(public value: string). I would expect that to also be included in the model.

I'll look into this and see if it can be done without introducing unnecessary complexity.

@gms1 I've opened up a pull request to support this behavior: #14

Since you opened this issue, please take a look at those changes and provide some feedback. I've added a suite of tests for these changes and done some manual testing, but I'd like your input.

Thanks!
