Wraps an Array of Strings. The Array describes a path from the
root of the syntax tree to a token including all scope names for the entire
path.
Methods that take a ScopeDescriptor will also accept an Array of String
scope names e.g. ['.source.js'].
You can use ScopeDescriptors to get language-specific config settings via
Config::get.
You should not need to create a ScopeDescriptor directly.
See the scopes and scope descriptor guide for more information.
