Default to random key
First pass on making Keys nicer
Add a bunch of stuff and tests
Different hex checking
Add public key support and a test for address generation
First stuff using ECDSA points
Move IncompatibleNetworkException outside of WIFKey
Add ECDSA points for pubkey
Move network constants to network module
Use base58's b58encode_check and b58decode_check
Remove Base64 key stuff, since nobody does b64
Significant refactor. init methods now take longs. More from_xx methods
Add test for leading zeros in hex key
Ensure hex keys are 0-padding to 64 chars
No sense having a separate AddressKey class
Break out utils module
