added option for minPixel

[vedadb]

Added option "minPixel" not to need to do Option 1. Option 2. just skips the generation of grains object so slight speed up. (performs the same tesselation first run as second) Option 3 and 4 perform first modified tesselation/graincalculation first run - either as scalar ebsd map (spatialDecomposition.m) or unit cell, and they produce the same grain map. - "major speed up". Please try

e = ebsd; e= e.gridify; e1 = e;

Option 1: tic [g,e.grainId] = calcGrains(e); e(g(g.grainSize<5)) = []; e=e.gridify; g=calcGrains(e); toc

Option 2: tic g1 = calcGrains(e1,'minPixel',5); toc

Option 3: tic g2 = calcGrains(e1,'minPixel',5,'byScalar'); toc

Option 4: tic g3 = calcGrains(e1,'minPixel',5,'byUnitCell'); toc
