function sliceloop(sdir)

% SLICELOOP loops over user-specified 3d slices in given direction.
%
%     SLICELOOP(SDIR) loops over slices in direction specified by SDIR.
%     SDIR may be 'x', 'y', or 'z'.
%
%     SLICELOOP, by itself, prompts the user for a direction (either x,y or z)
%     and loops over slices in that direction.
%
%     At start of loop, all slices in specified direction are hidden.
%     Then slices are viewed, one at a time, in specified direction.
%     The visibility of slices in any of the other two directions
%     will not be affected.
%
%     SLICELOOP only loops over those slices specified by variables
%     xSliceCoords, ySliceCoords or zSliceCoords, in setplot3.m.
%
%     See also SHOWSLICES, HIDESLICES, SETPLOT3.
