= Acts as slugable readme
Generates a URL slug based on a specific fields (e.g. title).
A url slug is a string derived from a specific field which can the be used in a URL. For instance, a page with the title <tt>My page</tt> would have a URL slug of <tt>my-page</tt>.
The slug is generated on save and create actions. If the field has an existing URL slug (like when editing an existing record) the URL slug is preserved.
URL slugs are unique within the specified scope (or all records if no scope is defined). If the slug already exists within the scope, <tt>-n</tt> is added (e.g. <tt>my-page-0</tt>, <tt>my-page-1</tt>, etc...
== Installation
