/**
 * Instantiate an address from an address String or Buffer, a public key or script hash Buffer,
 * or an instance of {@link PublicKey} or {@link Script}.
 *
 * This is an immutable class, and if the first parameter provided to this constructor is an
 * `Address` instance, the same argument will be returned.
 *
 * An address has two key properties: `network` and `type`. The type is either
 * `Address.PayToPublicKeyHash` (value is the `'pubkeyhash'` string)
 * or `Address.PayToScriptHash` (the string `'scripthash'`). The network is an instance of {@link Network}.
 * You can quickly check whether an address is of a given kind by using the methods
 * `isPayToPublicKeyHash` and `isPayToScriptHash`
 *
 * @example
 * ```javascript
 * // validate that an input field is valid
 * var error = Address.getValidationError(input, 'testnet');
 * if (!error) {
 *   var address = Address(input, 'testnet');
 * } else {
 *   // invalid network or checksum (typo?)
 *   var message = error.messsage;
 * }
 *
 * // get an address from a public key
 * var address = Address(publicKey, 'testnet').toString();
 * ```
 *
 * @param {*} data - The encoded data in various formats
 * @param {Network|String|number=} network - The network: 'livenet' or 'testnet'
 * @param {string=} type - The type of address: 'script' or 'pubkey'
