create-new-analysis

#!/bin/bash

# This script creates a new almost-minimal analysis directory based on the examples
# directory. It will contain a new AnalysisModule and Selection class.
#
# Usage:
#   create-new-analysis VLQSingleTToH
#
# where MyAnalysis is the name of the subdirectory to create, which will also
# be the name of the github repository in UHH2. This name will also be used in class
# names, although that can be easily changed later.
