/**
 * Static builder for handling the parsing of Bip44 Paths.
 *
 * BIP44 is a particular application of BIP43.
 * It defines a hierarchy for deterministic wallets based on BIP32,
 * and the purpose scheme described in BIP43.
 *
 * A Bip44 path defines the following levels:
 * - m / purpose' / coin_type' / account' / change / address_index
