Cleans up interface (it's now a command line option) and renames project to "sqlcache" in the all-one-word style. Still has issues to do with concurrency, retrying transactions, and foreign function calls that either rely on state or have side effects.

val r = {A = 1, B = "Hi", C = 0.0}
val rA = r -- #A
val rB = r --- [A = _, C = _]

fun main () : transaction page = return <xml>
        {cdata rA.B}, {cdata rB.B}
</xml>
