Methods:

• public void check_clean ()

• public bool check_validity_m (MetaStruct? mstruct) throws Error
  If mstruct is not null, then checks that all the database objects referenced in the statement i actually referenced in mstruct (for example the table being updated in a UPDATE statement must exist in the connection's database for the check to succeed).
