oh-my-zsh Theme: ys for Clusters

This ys-clusters theme extends the oh-my-zsh default theme ys by Yad Smood with my needs for working with batch submission systems on large clusters.

Modifications

1. Most importantly, it reads environment variables to determine the current job id.
   Currently supported are Slurm, LSF / IBM Spectrum LSF, PBS. Let me know if you need support for more.
2. It adds Virtualenv information (currently quite ugly)
3. The $HOST variable can be overridden by a ~/.box-name file

Installation

Put the ys-cluster.zsh-theme into $ZSH/custom/themes/ and activate it by setting ZSH_THEME="ys-cluster" in your ~/.zshrc.
