Computes the relative path to this path from
base_path using web path rules.
Path relativeToWeb(Path) (
if (isInstanceOf!(GenericPath, Path));
The difference to
relativeTo is that a path not ending in a slash
will not be considered as a path to a directory and the parent path
will instead be used.
|path||The destination path|
|base_path||The path from which the relative path starts|
