Problem 86. Renaming a field in a structure array
MATLAB has a setfield and a rmfield, but not a "rename field". You need to write one for this problem.
Example
Suppose
s(1).foo = 1; s(1).bar = 'one'; s(2).foo = 2; s(2).bar = 'two';
and you want the field "bar" to be renamed "baz". Given the inputs s, oldField, and newField, you must return this output structure with all the data still in place.
s(1).foo = 1; s(1).baz = 'one'; s(2).foo = 2; s(2).baz = 'two';

Does "All the data still" mean, that the fields are not re-ordered? A lot of the solutions change the order of the fields.
Currently, Matlab has the function renameStructField.
