ebsd('phase') of EBSDsquare kill props on feature/grain3d

[kilir]

Hi Ralf, on the feature/grain3d branch, selecting ebsd by phase seems to result in loosing all the props.

Example:

mtexdata forsterite
ebsd = ebsd.gridify 
ebsd.prop

%ans = 
%
%  struct with fields:
%
%    bands: [336×732 double]
%       bc: [336×732 double]
%       bs: [336×732 double]
%    error: [336×732 double]
%      mad: [336×732 double]
%    oldId: [336×732 double]

ebsd('f').prop

%ans = 
%
 % struct with no fields.

Cheers, Rüdiger
