estimate GBND and GBCD from 2d boundary segments
Syntax
gbnd = calcGBND(gB,ebsd)
gbnd = calcGBND(gB,grains)% the gbcd for a specific misorientation
gbcd = calcGBND(gB,grains,mori)% use a specific halfwidth
gbnd = calcGBND(gB,ebsd,'halfwidth',10*degree)Given an EBSD the orientations on either side of a segment are looked up through gB.ebsdId, which is only meaningful while every segment still runs between one specific pair of pixels. smoothBoundary breaks that by default - it merges and resamples segments - so smooth with 'noSimplify','noRefine' before calling this, or pass the grain2d instead and work from the grain mean orientations.
Input
| gB | grainBoundary |

| odf | SO3Fun used for texture correction |
Output
| gbnd | S2FunHarmonic |
Options
| halfwidth | used for kernel density estimation |
| nonneg | use a nonnegative kernel |
