## /*
# @usage trackbranch [<branch_name>]
#
# @description
# This script allows an easy way to set the upstream for an existing branch.
#
# If there is a remote branch of the same name in existance, it will choose it.
#
# If it does not find a remote branch it will push the <branch_name> to the remote.
#
# It will then set the upstream for the local branch to the remote branch of the same name.
# description@
#
# @notes
# - It uses the git command git branch --set-upstream foo upstream/foo
# notes@
#
# @examples
# 1) trackbranch
# 2) trackbranch foo
