Add section on using ChromePHP Log Writer
Fixed some syntax errors

The `Zend\Code\Generator\ClassGenerator` class does not have a `setMethod` method which takes a `Zend\Code\Generator\MethodGenerator` param. Instead the `addMethodFromGenerator` method exists.

Also an object of type `Zend\Code\Generator\FileGenerator` cannot be echoed, the `generate` method should be called instead.

Added Composer Package Name

I had a difficult time locating the correct value to use in Composer to require this package.

For me, though, as a newbie to ZF, having the composer package name by the discussion of installing it with Composer is helpful. Thanks!
