[VOTE] Modularisation, Gradle and source code restructuring

[Martin Desruisseaux]

Hello all

Following on the proposal posted as a discussion thread one week ago, a 
pull request has been created with the specific changes:

   https://github.com/apache/sis/pull/37

Given that this is a big change for Apache SIS developers (but not for 
users of the binaries), I think that we need a vote. So this is a vote 
for merging the above-cited pull request. I will keep the vote open for 
one week, until Monday August 14th.
