More natural interface for SQLite wrapper

[Alexey Romanov]

I am working on my fork of the Erlang wrapper for SQLite 3
(https://github.com/alexeyr/erlang-sqlite3) and one this question
arose: which Erlang values should correspond to SQLite types
(http://www.sqlite.org/datatype3.html) TEXT and BLOB? Currently TEXT
is any iodata (i.e. binary or iolist), and BLOB is represented by
tuple {blob, Binary}. The alternative would be to allow only iolists
as TEXT, and represent blobs as binaries. Which would be easier to
use, in your opinion?

Yours, Alexey Romanov
