Introduction: example referring to CMS

[ysmartin]

Introduction

functionality to customize the accessibility checks that are automatically carried out
for webmasters to monitor the overall accessibility of the website.

Suggestion: The reference to customizing automatic checks has been removed. Provide instead another example of automatic integration of accessibility in a continuous integration environment.

Rationale: Maybe we want to strip out any reference to automatic tests from the introduction, and we do not want to talk yet about test selection. But the idea of integrating accessibility evaluation in an automated testing workflow is a much more powerful example in the context of a CMS, rather than simply talking about monitoring the accessibility, in such a generic way.
