Updates column names of a table according to the mapping in second dictionary table. The dictionary table needs to contain two columns, one of which contains the lookup (i.e. the column names of the table to be renamed), the other column containing the new column names. The lookup column may be the RowID column.
If the assigned new value in the value column is missing, the original column name will be retained. If the lookup column contains duplicates of the original column names, the node will fail.
