=head1 Construction
-Derived classes should decalare their attributes using the C<_attributes>
+Derived classes should declare their attributes using the C<_attributes>
method. They can then inherit the C<init> method from here which will call
accessors of the same name for any values given in the hash passed to C<new>.
Note that you will have to impliment the accessors your self and we expect perl

Get or set the objects "extra" attibutes (e.g., "ZEROFILL" for MySQL fields).
-Accepts a hash(ref) of name/value pairs to store; returns a hash.
+Call with no args to get all the extra data.
+Call with a single name arg to get the value of the named extra attribute,
+returned as a scalar. Call with a hash or hashref to set extra attributes.
+Returns a hash or a hashref.
