feat(fugit): added fugit and fugitclean scripts for working with student repos

fugit.sh

+#!/bin/sh
+
+if [ $# -gt 2 ]; then
+    printf "Usage: %s [branch] [reponame]" $(basename $0) >&2
+    printf "Default branch name will be read from comments.txt" >&2
+    printf "Default reponame will be npvp-exercises" >&2
+    exit 1
+fi
+
+if [ -z $2 ]; then
+    repo_name=`echo $PWD | sed 's/.*(\([a-z0-9]*\))$/\1/'`
+    repo_name="$repo_name/npvp-exercises"
+else
+    repo_name=$2
+fi
+
+if [ -z $1 ]; then 
+    # read branch name from comments.txt
+    branch_name=`cat comments.txt`
+     
+else
+    branch_name=$1
+fi
+
+`git clone -b $branch_name git@git.imp.fu-berlin.de:$repo_name git-solution`

fugitclean.sh

+#!/bin/sh
+# this script cleans all checked out repositories when called from the same folder that contains the grades.csv
+# or a singular checked out repo when called from within a student folder
+
+find -type d \
+    -wholename "*/git-solution" -prune \
+    -execdir sh -c "rm -rf ./git-solution/" {} \;
+
