/**
* Represents a muxed account for transactions and operations.
*
* A muxed (or *multiplexed*) account (defined rigorously in
* [CAP-27](https://stellar.org/protocol/cap-27) and briefly in
* [SEP-23](https://stellar.org/protocol/sep-23)) is one that resolves a single
* Stellar `G...`` account to many different underlying IDs.
*
* For example, you may have a single Stellar address for accounting purposes:
* GA7QYNF7SOWQ3GLR2BGMZEHXAVIRZA4KVWLTJJFC7MGXUA74P7UJVSGZ
*
* Yet would like to use it for 4 different family members:
* 1: MA7QYNF7SOWQ3GLR2BGMZEHXAVIRZA4KVWLTJJFC7MGXUA74P7UJUAAAAAAAAAAAAGZFQ
* 2: MA7QYNF7SOWQ3GLR2BGMZEHXAVIRZA4KVWLTJJFC7MGXUA74P7UJUAAAAAAAAAAAALIWQ
* 3: MA7QYNF7SOWQ3GLR2BGMZEHXAVIRZA4KVWLTJJFC7MGXUA74P7UJUAAAAAAAAAAAAPYHQ
* 4: MA7QYNF7SOWQ3GLR2BGMZEHXAVIRZA4KVWLTJJFC7MGXUA74P7UJUAAAAAAAAAAAAQLQQ
*
* This object makes it easy to create muxed accounts from regular accounts,
* duplicate them, get/set the underlying IDs, etc. without mucking around with
* the raw XDR.
*
* Because muxed accounts are purely an off-chain convention, they all share the
* sequence number tied to their underlying G... account. Thus, this object
* *requires* an {@link Account} instance to be passed in, so that muxed
* instances of an account can collectively modify the sequence number whenever
* a muxed account is used as the source of a @{link Transaction} with {@link
* TransactionBuilder}.
*
* @constructor
*
* @param {Account} account - the @{link Account} instance representing the
* underlying G... address
* @param {string} id - a stringified uint64 value that represents the
* ID of the muxed account
*
