In the transition phase

js-vine.js has been renamed to abvn.js and relicensed under the MPL 2.
The old code and documention has been moved to a temporary legacy folder
while the documention, copied from legacy folder into the root directory
has been restructed. The demos in the new documention folder still use js-
vine.js and need be to fixed to abvn.js. The documention itself will be
revamped following the change.
