post-checkout hook script to change database.yml config
#!/bin/bash
#
# This hook changes database name prefix in config/database.yml based on the branch
# being checked out. It expects the database name prefix to be on word followed
# by a dash.
# If the branch name has a dash, it will take the new database name prefix as the
# name of the branch before the first dash e.g. ihas-feature => ihas
# This allows multiple branches to use the same database.
#
# File checkouts are ignored. Checking out a remote branch or a different ref
