Ramlwrap

Thanks to Emanuele Franceschini and Tim Harvey, RamlWrap 2.3(+) now supports multiple examples in both documentation and stubs.

For the stubbed approach, if you're using early versions of python, "which" example used is 'undefined' due to Python2's dictionary ordering, but hopefully by this point in time everyone is on Python3, which the first one is being used.

To Quote Tim:

> New ramlwrap allows you to specify a validation error handler that also receives the request object so that we can have different logging or other behaviour depending on api being called

also dependency update for pyyaml for its security release.

Emad88 has kindly added in a reference scanner in the documentation area which allows for more accurate documentation pages to be generated when using schema.

The main feature release here is of the RamlWrap Docs (which can be seen on the test). More examples to come.

This release (with many thanks to Jamian and Rizzle93) comes with two main new usability features, and a couple of technology fixes:

* Dynamic URLs (which makes REST api's much easier to write). This is now done by changing your function map to not just be a pointer but an array passed in containing both the function and a regex to use for that variable:
* GET and POST urls: in previous versions the api only supported a GET or a POST for a particular url, but now it supports pretty much all versions (although examples of HEAD and UPDATE etc we could do with some feed back and real world examples of people using them

Technology changes:
* The dependancy upon pyraml has been dropped which allows us to support a wider range of raml edge cases without waiting for pyraml to be updated.
* Now should support from Django 1.7 - 1.11 for Python 2.7 and Django 1.9 - 2.0 for Python 3.
