- added normals to pearl1.cloud, and added run.log
- added some scenes and runlogs
energyFunctors.h
    - normalized smoothness cost to 1..0, pw cost is now (1+spatial_weight) * sqrt(angle)

problemSetup.hpp
    - datacost modulation by trending directions: .1 + .9 * ((#did/n)^2 - 1.)^6
segmentation.hpp
	- planes get created from 5 points up
