Re-implemented base token in LLL.
Functionality is on-par with previous Solidity implementation: that is, it barely works as a stand-alone single token, without dispatcher delegation or registries.
Solidity implementation of base token, as-is. Registry still a stub.
To allow easy upgradability, a much lower-level approach seems required. Most importantly, dealing away with Solidity's storage layout scheme, and library use quirks.
Next version is likely to be in LLL. I do not see this as a setback: contrary, this furthers understanding of the issue at hand.
See notes in docs/2017-11-28-token-storage-layout.md
Use actual function instead of placeholder var.
git uses config-mode # to mark comments, rendering Markdown impossible for timestamping. Python users rejoice!..
