> CONCAT2 is similar to CONCAT function, which simply a string concatenation of all the provided parameters, however, it allows specifying a separator to be used between the concatenated strings as a first argument, and accepts arrays of strings that get flatted and concatenated.
>  
> If a single argument only is provided with the separator, then the separator is not used, and only a single string is returned.
>  
> Examples:
> {code:java}
>  concat2("-", "1", "2")        -> "1-2"
>  concat2("-", "1", ["2", "3"]) -> "1-2-3"
>  concat2("-", "1")             -> "1"
>  concat2("-", ["1"])           -> "1"
> {code}
