FIX missing parameters in v2.listEntities() documentation

[fgalan]

Addresses the documentation gap described in issue #27

The repository has another NGSI.js file in ngsijs/dist/ directory. I haven't touched that one as I don't know what it is :) but if the same change needs to be propagated in it, just tell me.

Please @aarranz review. Thanks!

I haven't touched a single line of real code. Maybe the coverage reporter should be configured to not take into account comments? ;)

Hi @fgalan!

First, thank you very much for the contribution.

The repository has another NGSI.js file in ngsijs/dist/ directory. I haven't touched that one as I don't know what it is :) but if the same change needs to be propagated in it, just tell me.

The NGSI.js file inside the ngsijs/dist/ directory is the latest released stable version. So your changes will be propagated into that file just after we make a new release.

Coveralls is already ignoring code comments, but I have found the problem. It was related to one travis jobs failing to start xvfb (it seems that has something has been changed on the Travis side). I've added a commit into your PR and now coverage is fine (although coveralls still reports an invalid coverage value for the PR).

Taking that into account, I have merged your changes 😃.

You're welcome! ;)
