Lots of phpDoc comments added to methods with no content; they should be removed or have comments provided, shouldn't they?

Unfortunately there are major issues with the new code, the approach this class has taken (generally) and arguably the endpoint URL structure.

The constructor sets up a base_uri like this:

'base_uri'      => "{$api_url}/protected/json/"

The request URL passed into the OneTouch endpoints is similar to:

onetouch/json/users/{$authy_id}/approval_requests

So this produces a request URI of:

"{$api_url}/protected/json/onetouch/json/users/{$authy_id}/approval_requests"

This is incorrect.

The only realistic way forward, I think, could be to change the base URI to simply:

"{$api_url}/"

And then update every request URI in this class, and others, to be, e.g.

'protected/json/users/new'

I need this code anyway, so I may submit a new pull request.

As I side note, I sort of question the logic behind the OneTouch stuff not being under, e.g. protected/json/onetouch in the first place, but I guess that's too difficult to change now.

@chrisdeeming I'll take a look at your comments and modify the PR according to them. Hopefully it will be ready this weekend.

Thanks for your help!
