BIP44 implementation example

This example implements a single perl function bip44_get_derived_key_from_mnemonic. This function performs an extended key derivation with paths specified in bip44 document. Base key is taken from mnemonic code with optional password. A resulting scalar variable is a basic private key instance, which can be used for message signing, verification and address generation.
