structcombine(struct1, struct2)
function combined = structcombine(struct1, struct2)
%STRUCTCOMBINE
%   COMBINED = STRUCTCOMBINE(STRUCT1, STRUCT2)
%
%   Crash structs together, using STRUCTAPPEND to resolve overlapping fields.
%   This will take all the fieldnames of STRUCT2 and add them to STRUCT1, then
%   copy all the data of STRUCT2 into the new expanded STRUCT1, including data
%   in higher dimensions of struct2.
%
%   For example, if STRUCT1 is:
%       struct1.x = 0
%
%   And STRUCT2 is:
%       struct2.y = 0
%       struct2(50,50).y = 0
%
%   Then the result, COMBINED is a 50-by-50 struct array with fields x and y and
%   almost no data except for fields combined(1).x, combined(1).y, and
%   combined(50,50).y, all of which are set to zero.
%
%   For example of overlapping fields, if:
%       struct1.x = 0
%       struct2.x = 0
%   
%   Then combined.x will be cell array {0 0}.
