// Ensemble is a collection of nodes instantiated within a test.
//
// Create a new ensemble with:
//
// ens := kit.NewEnsemble()
//
// Create full nodes and miners:
//
// var full TestFullNode
// var miner TestMiner
// ens.FullNode(&full, opts...) // populates a full node
// ens.Miner(&miner, &full, opts...) // populates a miner, using the full node as its chain daemon
//
// It is possible to pass functional options to set initial balances,
// presealed sectors, owner keys, etc.
//
// After the initial nodes are added, call `ens.Start()` to forge genesis
// and start the network. Mining will NOT be started automatically. It needs
// to be started explicitly by calling `BeginMining`.
//
// Nodes also need to be connected with one another, either via `ens.Connect()`
// or `ens.InterconnectAll()`. A common inchantation for simple tests is to do:
//
// ens.InterconnectAll().BeginMining(blocktime)
//
// You can continue to add more nodes, but you must always follow with
// `ens.Start()` to activate the new nodes.
//
// The API is chainable, so it's possible to do a lot in a very succinct way:
//
// kit.NewEnsemble().FullNode(&full).Miner(&miner, &full).Start().InterconnectAll().BeginMining()
//
// You can also find convenient fullnode:miner presets, such as 1:1, 1:2,
// and 2:1, e.g.:
//
// kit.EnsembleMinimal()
// kit.EnsembleOneTwo()
// kit.EnsembleTwoOne()
