Prokee Module: path
The module path provides functions for manipulating strings which holds paths.
A path may relate to a path within the file system, but can also represent a path within a graph. This module handles paths, which are provided as a null-terminated string.
If the edges of a graph are named with strings, f.e. edge1, edge2, .... Then a path string could be constructed by appending the names of consecutive edges and separate them with a special character, as f.e. the '/' character. Then we get "edge1/edge2/edge3" as a possible path string.
For a path within a file system, we append a '/' character to all directory names, by convention. Therefore the path C:/Users/Max/Documents/ is considered to be a path to a directory, while C:/Users/Max/Documents/mydoc.pdf describes a path to a file.
