* ## Overview
*
* @name Keyring
* @summary Keyring management of user accounts
* @description Allows generation of keyring pairs from a variety of input combinations, such as
* json object containing account address or public key, account metadata, and account encoded using
* `addFromJson`, or by providing those values as arguments separately to `addFromAddress`,
* or by providing the mnemonic (seed phrase) and account metadata as arguments to `addFromMnemonic`.
* Stores the keyring pairs in a keyring pair dictionary. Removal of the keyring pairs from the keyring pair
* dictionary is achieved using `removePair`. Retrieval of all the stored pairs via `getPairs` or perform
* lookup of a pair for a given account address or public key using `getPair`. JSON metadata associated with
* an account may be obtained using `toJson` accompanied by the account passphrase.
