Automatically control Leiningen project version based on Git and system metadata.

1. Add suitable base tag to repository

   git tag -a v0.0.0 -m "initial version"

2. Add plugin definition to project.clj

   (defproject foo/bar "_"  ; replace project version string with underscore
     ...
     ; add the plugin dependency
     :plugins [[fi.polycode/lein-git-revisions "LATEST"]
               ...]
     ; add recommended default configuration
     :git-revisions {:format        :semver
                     :adjust        [:env/revision_adjustment :minor]
                     :revision-file "resources/metadata.edn"}
     ...)

Project version must be a string for IDE compatability. For example Cursive makes assumptions based on the version always being a string.

Further configuration options are described in depth at git-revisions core library's README.
