Change Directory (cd) Overload

Overloads 'cd' to allow changing to a directory specified by a file in your MATLAB path.

Overloads built-in MATLAB function 'cd', enabling changing the directory to one in the MATLAB path by using a filename in that directory. For example, if 'awesome.m' is somewhere in your MATLAB path, this function enables a command like cd('awesome')

MATLAB will give you warnings that this function has the same name as a MATLAB builtin. Use warning('off','MATLAB:dispatcher:nameConflict'); (like in startup.m) to turn off

It would be interesting to combine this function with the features in Brendan Hannigan's Cool CD: https://www.mathworks.com/matlabcentral/fileexchange/5959-cool-cd-change-directory
