Adds ocaml-sqlite3EZ and its dependency ocaml+twt

ocaml+twt is an alternative syntax for OCaml that uses indentation to group
multi-line expressions, like Python and Haskell.

sqlite3EZ is a thin wrapper for sqlite3-ocaml with a simplified interface. Query
results are processed with a functional map/fold, transactions are
aborted by exceptions, resource management is handled by the garbage
collector, etc.
