compareStruct(a,b)

% compareStruct - Compare Structs fields
% Description : returns logical 1 (true) if the input structs have the same
% fields, and logical 0 (false) otherwise, no matter their content.
%
% Syntax:   = compareStruct(a,b)
%
% Inputs:
%    a - First Struct
%    b - Second Struct
%
% Outputs:
%        B - Boolean for the Struct type equality test
%
% Example: 
%    struct1.x = 1; struct1.y = 5;
%    struct2.x = 2; struct2.y = 10;
%    B = compareStruct(struct1,struct2)
%
% Other m-files required: exist, strcmp, numel, fieldnames
% Subfunctions: none
% MAT-files required: none
