3rd & 4th: Paper texture and experiment work, cleanups

Today: need to think of a way of interactively modifying
the parameters of papermill-created papers.

How about creating a custom rng class that would take
the name of the random parameter as an argument, i.e.
something like

        a = rng.getFloat("pass0.foobar")
        v = rng.getIntVec("pass0.mainaxis")
        c = rng.getColor("pass0.color0")

Then, after creating a paper, the rng object could be
asked for a list of parameter names and values.
The values could be changed and given to a new rng
object as predefined values.
