=head1 DESCRIPTION

This class is a helper for constructing BIP44-compilant key derivation paths.
BIP44 describes the mechanism the HD (Hierarchical Deterministic) wallets use
to decide derivation paths for coins. BIP49 and BIP84 are constructed the same
way, but used for compat and segwit addresses respectively.

Each coin has its own C<coin_type> constant, a list of which is maintained
here: L<https://github.com/satoshilabs/slips/blob/master/slip-0044.md>.
