new
(new ['flg|num] ['typ ['any ..]]) -> objCreates and returns a new object.
If flg is given and non-NIL, the new object will be an external symbol (created in database file 1 if T, or in the corresponding database file if num is given).
typ (typically a list of classes) is assigned to the VAL, and the initial T message is sent with the arguments any to the new object.
If no T message is defined for the classes in typ or their superclasses, the any arguments should evaluate to alternating keys and values for the initialization of the new object.

(new! 'typ ['any ..]) -> objTransaction wrapper function for new. (new! '(+Cls) 'key 'val ...) is equivalent to (dbSync) (new (db: +Cls) '(+Cls) 'key 'val ...) (commit 'upd).
