Enables gitlogg to be distributed via npm
`npm install -g gitlogg` will put it on your path Script is now agnostic to the pwd in which it's invoked `.js` is pre-transpiled so babel isn't required at runtime - set environment variable GITLOGG_DEV to enable runtime transpilation and avoid the build step Instead of a hardcoded `yourpath` variable, each positional argument to `gitlogg` is a repository path. - You can easily `gitlogg ./myrepos/*/` to process all repositories in a directory `.js` reads and writes from file descriptors 3 and 4; these are managed by bash script
