Transitive includes not supported

[lfrancke]

I decided to open a new issue but it is related to this comment #25 (comment)

The problem is that we have a XSD (A) that includes another one (B) which in turn imports a third one (C).
Currently when A references something from C it is treated as a UnsolvedReference.

According to this post on StackOverflow it's not entirely clear whether this should be supported or not: https://stackoverflow.com/questions/13735887/use-type-from-xsd-imported-from-import

So this is a feature request: It'd be great if XsdParser could (maybe optionally) process transitive includes.

Hello,

I'm also not sure if XSD should support that or not. I'm using Intellij and if I'm using:

A including B
B including C

It shows the elements of C in A.

On the other hand if I have:

A importing B
B importing C

It only shows elements from B on A.

Apart from that, I've had to improve some stuff to solve #25 which have also "resolved" this problem.

I've introduced some use cases and tests (Transitive Includes, Transitive Imports) related with this issue, you can take a look if you want.

I've also performed a new version where all of this is available, (1.1.0), give it a shot.

Thanks for using the library and for the feedback!

Thank you for implementing this! Unfortunately, I'm not currently able to test this with my original data as I've lost access to it.
