/*
HTTP is a Client implementation that communicates with a Tendermint node over
JSON RPC and WebSockets.

This is the main implementation you probably want to use in production code.
There are other implementations when calling the Tendermint node in-process
(Local), or when you want to mock out the server for test code (mock).

You can subscribe for any event published by Tendermint using Subscribe method.
Note delivery is best-effort. If you don't read events fast enough or network is
slow, Tendermint might cancel the subscription. The client will attempt to
resubscribe (you don't need to do anything). It will keep trying every second
indefinitely until successful.

Request batching is available for JSON RPC requests over HTTP, which conforms to
the JSON RPC specification (https://www.jsonrpc.org/specification#batch). See
the example for more details.

Example:

	c, err := New("http://192.168.1.10:26657")
	if err != nil {
		// handle error
	}

	// call Start/Stop if you're subscribing to events
	err = c.Start()
	if err != nil {
		// handle error
	}
	defer c.Stop()

	res, err := c.Status()
	if err != nil {
		// handle error
	}

	// handle result

// requests (as per https://www.jsonrpc.org/specification#batch). Do not

//
// Batching of HTTP requests is thread-safe in the sense that multiple
