fun concatenatePaths(path1: Path, path2: Path): Path? (source)
Concatenate two given paths.
Example: Let's say we've got two paths: Luuk - worksFor - Drieam and Drieam - earns - Money.
So our result should be: Luuk - worksFor - Drieam - earns - Money.
We have to strip out once occurrence of Drieam, otherwise we'll have a duplicate Node.
path1 - The first part of the to-be concatenated path.
path2 - The last part of the to-be concatenated path.
Return
The concatenation of the two given paths.
