Add helper trait to provide type-hinting for zend-view

[thexpand]

In favor of the following proposal:
zendframework/zend-view#102

I'm not sure about this one, because there is already a doc-block @method in Zend\View\Renderer\PhpRenderer. Take a look:
https://github.com/zendframework/zend-view/blob/master/src/Renderer/PhpRenderer.php#L45

[froschdesign]

The usage of this trait must be explained in the documentation.

[froschdesign]

Btw. Please use the develop branch for new features.

I suggest adding the docs as a sub-section of the main section View Helper.
Maybe at the bottom?
See more about the naming in my comment here: zendframework/zend-i18n#102 (comment)
Here's a link to the main section in the docs: https://docs.zendframework.com/zend-mvc-plugin-flashmessenger/flash-messenger-view-helper/

Maybe at the bottom?

For this single page is bottom okay.

@froschdesign
I've placed the docs at the bottom, without block quotes, in contrast to the other PRs (zendframework/zend-i18n#102, zendframework/zend-form#217)
