DefaultFieldMapFunc maps a field name to a DB column name.
The mapping rule set by this method is that words in a field name will be separated by underscores
and the name will be turned into lower case. For example, "FirstName" maps to "first_name", and "MyID" becomes "my_id".
See DB.FieldMapper for more details.
