HD derivation path
The HD derivation path is a string that makes it easy to handle multiple crypto currencies (assuming they all use the same signature algorithms), multiple blockchains, multiple accounts, and so on.
HD derivation path can have as many parameters as needed, and using different values for the parameters, we can produce different group of addresses and their associated keys.
By default, LightWallet uses the m/0'/0'/0' derivation path. Here, /n' is a parameter, and n is the parameter value.
Every HD derivation path has a curve, and purpose. purpose can be either sign or asymEncrypt. sign indicates that the path is used for signing transactions, and asymEncrypt indicates that the path is used for encryption and decryption.
