MergeCell

MergeCell takes any number of cell vectors (contain the same datatype) and concatenates their contents into one big cellvector
Any signleton inputs are expanded as needed, these inputs can be 1x1 cells or the contained datatype itself

Example: To add some information about fit to plot legend, we'd wan't to append information about the fit to the line labels:

linelbls = {'line a','line b','line c'};
slope = [.9 1 4.2];
slopetxt= arrayfun(@(x) sprintf('%.3f',x),slope,'UniformOutput',false);

leglbls = MergeCell(linelbls,', slope: ',slopetxt);
% leglbls = MergeCell(linelbls,{', slope: '},slopetxt); would be equivalent
