#join(*parts_or_path) ⇒ ElementPath

Returns a new path composed by the given parts

Examples:

Extend a path with an string

path = ProfilePath.new("general")
path.join("mode") #=> ProfilePath.new("general", "mode")

Combine ProfilePath and strings

path = ProfilePath.new("general")
suffix = ProfilePath.new("mode")
