Create repo for COUCHDB-3021 so it will hopefully get picked up

[SCdF]

https://issues.apache.org/jira/browse/COUCHDB-3021 has not been picked up by the couch guys, so maybe we should make it easier to understand by writing a minimal case repo they can use to reproduce the problem:

• project that pushes a ddoc into couch
• and generates ~10,000 documents with some data you could filter on
• that ddoc would have two erlang filters
  • one that simply checks for the data and filters on it
  • one that does the above but also has a lot of extra pointless erlang cruft that will never get executed (eg switch on true and then have a bunch of other cases for things that will never match) to increase the erlang size

With that we should be able to provide 'nix time curl ... commands that show that the first filter goes significantly faster than the second, even though the same code executes.

hi frand @estellecomment, please triage before the end of this sprint. :parrot_conga::parrot_conga::parrot_conga:

We're not using Erlang filters any more. Closing.
