String matcher

Added a String Matcher for business needs: match a businesas with queries that possibly refer to its name.
@ldacosta this should be implemented as something like
```scala
trait Eval[T] extends Wrapper[T]
implicit object Matcher_Url_Eval extends Matcher[Url, Eval] {
  def isCloseEnough: Eval[Url] => Eval[Url] => Eval[Boolean]
}
```
