STRPAD String Pad for Matlab

Simple function for padding strings with any number of char either at the start or the end

This has probably been created by other users, it can also be done easily with printf, but it is not core Matlab (that I know of). Since I use it as is in some of my other libraries so I was asked to add it here.
