new functionality: gml 3.2 and complex features

[Niels Charlier]

Hello,

I have written two patches for open layers:

* support for GML 3.2

* support for parsing complex features

I was wondering if the community would be interested in me contributing these to the codebase.

The first one simply adds a whole new format, so it is a very safe addition.

The second one replaces an existing function: ol.format.GMLBase.prototype.readFeaturesInternal
however my implementation of this function is a generalisation of the current implementation,

and it is thus fully backwards compatible with how simple features are parsed now.

I don't know if there is some kind of testing mechanism in place to proof my changes don't break anything.

I could make one or two PRs on github, let me know i there is interest and what I need to do in order to get it approved, .

Kind Regards

Niels

Thanks. Unfortunately I had to combine them in one PR because the two
patches are interdependent and I can't do much about that (GML3.2 must
also support complex features). I have added test cases for all new
functionality.

I have noticed in the meantime however there was already an old PR for
GML3.2 support that never got approved :/

Kind Regards

Niels
