[x] HTML import
[x] Flatten Seq
[x] Read commandline flags
[x] Measure exps
[x] catch exceptions in opts
[x] Stop if opts are doing nothing
[ ]  - actually, we should have a blow-up optimization if
	we're not doing anything; we can start perturbing
	the expression in the hopes that it will enable
	optimizations (but always save our best exp).
[x] automatically find examples where an optimization fails
[x] commandline param which disables all but a list of opts.
[ ] handle blowup opts

[ ] Maybe joe's thing can move non-commuting tags towards the middle
[x] smarter about ordering of opts
[ ] use same representation for opts when possible
[x] make lilvalidate faster
[ ] fix parser for space/speed
[x] <B><PL><B>e</B></PL>x</B>
[ ] Poly/ML
[ ] Charlie's thing
[x] move whitespace inner
[x] FINISH IN TIME!!
[ ] workaround slow-slow validate
