Mutable Document Path
Provides an interface to specify a path to a key in a document that you can then call various update functions on. You obtain a DittoMutableDocumentPath by subscripting a DittoMutableDocument and you can then further subscript a DittoMutableDocumentPath to further specify the key of the document that you want to update.
Used to specify an index in the array at the preceding key-path specified through the subscripting defined previously. You can subscript the return value further to access a further nested key in the document and eventually perform an update operation.
