option to integrate through JS + divs (Google Ad Manager)

[Ivshti]

Consider a new integration option, where you insert a JS in your page and also insert <div>s for every placement. This is actually how most ad networks work.

Pros:

• no <iframe>, which also makes it friendlier to Google Ad Manager
• we can vaguely control the placement we do that via 79ad0be
• we can detect whether it's in the viewport

Cons:

• slightly more difficult integration
• has to init an iframe to read from the AdEx Profile, but then every domain can read from the AdEx profile... this might not be so bad, since every publisher can do you a service by accessing this info; alternatively the iframe can encrypt it for the market and we can share that

Is the latest merge deployed? I will need it in order to make a sample integration with google ad manager and describe on how it can be done to Nadia.
