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 (optional) foreign key enforcement
  * MEDIUM
- implement write support for properties
  * EASY
- 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:
- simplify public API (separate "internal" and "external" api)
* separate table creation objects from existing metadata objects
* remove "simple" index support?
* remove "table traversal methods" from Table?
* enable integrity by default?
* remove import/export methods from Database?
* move database open/create options to DBBuilder
* tweak how import filters work to make them more flexible?
- tweak lookup apis (specify column vs column name)
- separate classes into more packages (api,builder,util,impl)
* remove debug log blocks
- add Row interface
- change savepoint to use table number instead of name?
* don't use columnimpl for creating tables
  * clean up columnimpl/tableimpl constructors
- add updateCurrentRow(Map), add updateRow(Row)
- sort out query types
- clean up javadocs
  - enhance public api classes
  - add @usage tags to util classes
* add unit tests for Row update/delete methods, add/update *FromMap methods
* add reason to unsupop throws for indexes
