taking out generated .go files from VCS

[darvin]

just creating it to track this possible improvement

so far options

1. do nothing, keep generated go files in git repo - cons - merge conflicts
2. investigate possible solution with using some of go package managers
3. investigate using git hooks (pre commit or post fetch whatnot) method - check if its implementable and if it plays seamless with go get http://github/.../expreduce that we want to keep
