- look in to making query and command's _handle a shared_ptr, so that query
5
and command classes can be copied.

- rename _bind_index and _column_index to _next_*

- change the transaction_guard interface so you can dereference it to
7
get to its transaction and the transactions take care of not
8
rolling back or committing when they already have done (as well as
9
resetting in-progress queries).

- add a rom::column() that can take a column name. This is nexessary
21
when doing a "SELECT *" and you don't know the column indicies. To
22
implement this, the first time it is called, a column-name-to-index
23
lookup would have to be built. This should be done in the query,
24
not the row. This means that the row will have to know it's query
25
(currently is copies its _handle) to be able to call column_index()
26
on it. Is this a problem?

- use sqlite3_db_mutex() to provide extended error information during
29
sqlite_error construction. The general procedure would be to lock
30
the db mutex, perform some sqlite3 command, check the error code,
31
throw an sqlite_error (whilst obtaining extended error info) and
32
then unlock the db mutex. Two options:

- make basic_statement and database keep a shared pointer to the
41
database handle so the classes can be made copyable. The wrappers
42
around the handle (implemented in sqlite::detail) can clean them up
43
after use. This will also make the implementation of rows (to get
44
round the forced non-dependency of rows on querys) a little easier
46
- A similar wrapper should be created for statement handles,
47
making basic_statements, querys and commands copyable. Could
48
weak_ptrs to these also be used in the database's list active
