Missing pieces:

- fix long text index entries (for new general sort order)
  * ???
- implement foreign key index creation & relationship creation
  * MEDIUM
- implement table creation w/ complex columns
  * MEDIUM
- implement table, column, index renaming
  * EASY
- implement table, column, index deletion
  * EASY - MEDIUM
- implement more comprehensive unicode compression write support
  * EASY? (have the code, do we trust it?)
- implement createReadOnlyTemp(InputStream) (delete temp file on close)
  * EASY
- figure out how msaccess manages page/row locks
  * MEDIUM

Refactor goals:
- tweak lookup apis (specify column vs column name)
- clean up javadocs
  - enhance public api classes
  * add @usage tags to util classes
- implement page buffering in PageChannel
  * need to implement logical flushing in update code (startUpdate/finishUpdate)
- implement "lazy" usage maps (load on first usage)?
- add typed getter methods to Row, PropertyMap
