…te Helper is (iltar)This PR was submitted for the master branch but it was merged into the 2.3 branch instead (closes#4344).Discussion----------[Templating] Added a sentence that explains what a Template Helper is| Q             | A| ------------- | ---| Doc fix?      | yes| New docs?     | no| Applies to    | all| Fixed tickets | n/aI found a SecurityHelper in the SecurityBundle. I was unsure what this helper was or what it was supposed to do. After some googling I've landed on the templating component documation. This is correct as the `HelperInterface` can be found in [the component](http://symfony.com/doc/current/components/templating/introduction.html#helpers). However, it doesn't explain what a helper is.After some searching, [the cookbook *does* explain what a helper is](http://symfony.com/doc/current/cookbook/templating/PHP.html#using-template-helpers). I've pretty much copied over the sentence from the cookbook to the component. If you have a better proposal, I can add that instead.Commits-------6cdecde [Templating] Added a sentence that explains what a Template Helper is

Since DBAL is database abstraction layer, and is defined in the document as such, to me it reads funny to have it as database abstraction layer layer. It sounds nitpicky, I know, but I find it an easier read this way. Also, the possessive DBAL stuck out ("DBAL's layer") as the DBAL doesn't own a layer, it is the layer.
