CSV export function console feedback

[Frisle]

The function needs feedback from the console to know if it is working or not

do ##class(bdb.sql.Dump).Dump("BI_Study.City", "/tmp/table.csv")

for the detailed info yes (right now), but if you pick up the %Status code returned from that method, you should be able to check whether it passed fine and if not, retrieve the error message.
