        Easy way to launch gRPC server with access to Django ORM and other handy stuff.
        gRPC calls are much faster that traditional HTTP requests because communicate over
        persistent connection and are compressed. Underlying gRPC library is written in C which
        makes it work faster than any RESTful framework where a lot of time is spent on serialization/deserialization.
        
        Note that you need this project only if you want to use Django functionality in gRPC service. 
        For pure python implementation [read this](https://grpc.io/docs/quickstart/python.html)
        
        * Supported Python: 3.4+
        * Supported Django: 2.X (let me know if you need Django 3 support)
        
        ## Installation
        
        ```bash
        pip install django-grpc
        ``` 
        
        Update settings.py
        ```python
        INSTALLED_APPS = [
            # ...
            'django_grpc',
        ]
        
        GRPCSERVER = {
            'servicers': ['dotted.path.to.callback.eg.grpc_hook'],  # see `grpc_hook()` below
            'interceptors': ['dotted.path.to.interceptor_class',],  # optional, interceprots are similar to middleware in Django
            'maximum_concurrent_rpcs': None,
        }
        ```
        
        The callback that initializes "servicer" must look like following:
        ```python
        import my_pb2
        import my_pb2_grpc
        
        def grpc_hook(server):
            my_pb2_grpc.add_MYServicer_to_server(MYServicer(), server)
        
        ...
        class MYServicer(my_pb2_grpc.MYServicer):
        
            def GetPage(self, request, context):
                response = my_pb2.PageResponse(title="Demo object")
                return response
        ```
        
        ## Usage
        ```bash
        python manage.py grpcserver
        ```
        
        For developer's convenience add `--autoreload` flag during development.
        
        
        ## Signals
        The package uses Django signals to allow decoupled applications get notified when some actions occur:
        * `django_grpc.signals.grpc_request_started` - sent before gRPC server begins processing a request
        * `django_grpc.signals.grpc_request_finished` - sent when gRPC server finishes delivering response to the client
        * `django_grpc.signals.grpc_got_request_exception` - this signal is sent whenever RPC encounters an exception while
        processing an incoming request.
        
        Note that signal names are similar to Django's built-in signals, but have "grpc_" prefix.
        
        
        ## Serializers
        There is an easy way to serialize django model to gRPC message using `django_grpc.serializers.serialize_model`.
        
        
        ## Testing
        You can call methods of your servicer and decode them using `django_grpc.serializers.deserialize_message` that
        will convert gRPC messages to python dictionary
