"crackle metric infinite"
replaces (dx^n + dy^n + dz^n)^(1/n) with max(dx,dy,dz)

"crackle tumbled"
randomly rotates, for each nucleus, the coordinate axes on which
dx,dy,dz are computed.  (has no effect on metric 2.)  without this, the
`grains' all line up alike, which is generally not how real minerals
behave.


i'll go be quiet now.
