Covering some basic topics I haven't seen elsewhere on Cody.
Given a string with extra spaces in front and/or in back, return a 'centered' version of the string (e.g.: ' MATLAB' -> ' MATLAB ')
Problem is incorrectly specified, according to the cases. 'Centering' seems to mean leave at most two spaces to either side, but otherwise center in the usual sense?
