This class is named with 'Concat...' but it doesn't seem to have anything
specifically to do with concat - or am I missing something? If it's generic,
then let's also name it generically.
> Support CONCAT function
> -----------------------
>
> Key: METAMODEL-224

> Project: Apache MetaModel
> Issue Type: New Feature

> Priority: Minor
>
> As we now support scalar functions it would be great to add support for a
> CONCAT function that allow us to concatenate and append strings to the query
> results.
