A subprovider that enables your dApp to send signing requests to a user's Ledger Nano S hardware wallet. These can be requests to sign transactions or messages.
+Ledger Nano (and this library) by default uses a derivation path of `44'/60'/0'`. This is different to TestRPC which by default uses `m/44'/60'/0'/0`. This is a configuration option in the Ledger Subprovider package.
+
##### Ledger Nano S + Node-hid (usb)
By default, node-hid transport support is an optional dependency. This is due to the requirement of native usb developer packages on the host system. If these aren't installed the entire `npm install` fails. We also no longer export node-hid transport client factories. To re-create this see our integration tests or follow the example below:

+##### Testing Subprovider + Ledger integration
+
+To run our integration tests you need a ledger configured with our development mnemonic seed.
+This is available in the top level package.json under `mnemonic`.
+Configure your ledger and run the integration tests. We assume a derivation path of `m/44'/60'/0'/0` and this is configured in the tests. To this setup and derivation path, your first account should be `0x5409ed021d9299bf6814279a6a1411a7e866a631`, exactly like TestRPC.

#### Redundant RPC subprovider
A subprovider which attempts to send an RPC call to a list of RPC endpoints sequentially, until one of them returns a successful response.
