BIP32 needs to be able to add two points on the secp256k1 curve. This functionality was not already being exposed from OpenSSL in bitcore. I have added an "addUncompressed" function to the Key class which takes in two points in uncompressed form, adds them, and returns the result. This is necessary for BIP32.
