bool	TryGet ( const TSharedPtr< FJsonValue >& RootValue, TSharedPtr< FJsonValue >& OutValue )	Attempt to retrieve the value specified by this Json Pointer from the provided JsonObject.
bool	TryGet ( const TSharedPtr< FJsonObject >& RootObject, TSharedPtr< FJsonValue >& OutValue )	Attempt to retrieve the value specified by this Json Pointer from the provided JsonValue.
bool	TryGet ( const TArray< TSharedPtr< FJsonValue >>& RootValues, TSharedPtr< FJsonValue >& OutValue )	Attempt to retrieve the value specified by this Json Pointer from the provided Json Array.
FString	UnescapePart ( const FString& Part )	Substitutes escaped characters in the Provided path with their original character (as per the spec).
