ThomaxV started a discussion on https://bitcointalk.org/index.php?topic=274182.msg2939599#msg2939599
about changing the HD derivation logic in electrum 2. The below post:
http://bitcoin.stackexchange.com/questions/37013/how-to-import-a-hd-wallet-from-an-extended-private-key
confirms that the format is actually m/c/i (and not m/44'/0'/a'/c/i)
so I have altered https://gist.github.com/romanz/4b32782bfc0ff4984713 accordingly:
tested to work with keys/addresses exported from electrum 2.7.0
note Electrum has a "gap limit" of 20, so loop @ level "c" to get the next 20 addresses
