- a fair amount of cleanup to the schema package, removal of ambiguous

methods, methods that are no longer needed.  slightly more constrained
useage, greater emphasis on explicitness.
- table_iterator signature fixup, includes fix for [ticket:288]
- the "primary_key" attribute of Table and other selectables becomes
a setlike ColumnCollection object; is no longer ordered or numerically
indexed.  a comparison clause between two pks that are derived from the
same underlying tables (i.e. such as two Alias objects) can be generated
via table1.primary_key==table2.primary_key
- append_item() methods removed from Table and Column; preferably
construct Table/Column/related objects inline, but if needed use
append_column(), append_foreign_key(), append_constraint(), etc.
- table.create() no longer returns the Table object, instead has no
return value.  the usual case is that tables are created via metadata,
which is preferable since it will handle table dependencies.
- added UniqueConstraint (goes at Table level), CheckConstraint
(goes at Table or Column level) fixes [ticket:217]
- index=False/unique=True on Column now creates a UniqueConstraint,
index=True/unique=False creates a plain Index,
index=True/unique=True on Column creates a unique Index.  'index'
and 'unique' keyword arguments to column are now boolean only; for
explcit names and groupings of indexes or unique constraints, use the
UniqueConstraint/Index constructs explicitly.
- relationship of Metadata/Table/SchemaGenerator/Dropper has been
improved so that the schemavisitor receives the metadata object
for greater control over groupings of creates/drops.
- added "use_alter" argument to ForeignKey, ForeignKeyConstraint,
but it doesnt do anything yet.  will utilize new generator/dropper
behavior to implement.
