Automatic package update via git pull #3
Description
As new scenarios are accepted into the package distribution, client end software will develop a sort of incompatibility. In v0.3, the server might serve all packages in the distribution, but the client may not have an updated distribution. In this case a user can be prompted to execute a scenario that it doesn't actually have a package for. This can be rectified by adding in an additional step to the client preceding all others to automatically git pull packages.
