Helpful 5 liner version of os makedirs

This script contains a function that creates missing directories for a given path and returns a normalized absolute version of the path.If the given path already exists in the filesystem the filesystem is not modified.

Otherwise makepath creates directories along the given path using the dirname() of the path. You may append a '/' to the path if you want it to be a directory path.

The usual os.makedirs functions and friends are not convenient enough. They don't return the path and they always throw errors if the directories already exist. Many times you just want to make sure that the directories of a path are really there without the fuss. And you want your directories to be os-independent (e.G. slash versus backslash issues).  makepath does all this.

if one of the directory parts of the path already exists and is e.G. a regular file the usual os.makedirs exceptions will be thrown which is ok because your path cannot be constructed.
