- attributes module and test suite moves underneath 'orm' package

- fixed table comparison example in metadata.txt
- docstrings all over the place
- renamed mapper _getattrbycolumn/_setattrbycolumn to get_attr_by_column,set_attr_by_column
- removed frommapper parameter from populate_instance().  the two operations can be performed separately
- fix to examples/adjacencytree/byroot_tree.py to fire off lazy loaders upon load, to reduce query calling
- added get(), get_by(), load() to MapperExtension
- re-implemented ExtensionOption (called by extension() function)
- redid _ExtensionCarrier to function dynamically based on __getattribute__
- added logging to attributes package, indicating the execution of a lazy callable
- going to close [ticket:329]
