Path, file directory

[samuelcolvin]

Allow paths, files and directories, check existence.

[samuelcolvin]

Needs:

• FilePath - path to a file with exists
• DirectoryPath - path to a directory which exists

Anything else (eg. FileInExistingDirectoryPath, or FileOrDirectoryPath) is probably overcomplicated and can be implemented via validators.
