hack - create a new feature branch off the main development branch
git town hack [-p] <branch_name>
Syncs the main branch and forks a new feature branch with the given name off it.
If (and only if) new-branch-push-flag is true, pushes the new feature branch to the remote repository.
Finally, brings over all uncommitted changes to the new feature branch.
<branch_name> The name of the branch to create. -p Prompts for the parent branch (instead of assuming the main development branch)
