Run script for linux easy installation

[kadavilrahul]

I have made shellscript run.sh for easy installation on linux. Kindly consider adding it.

#!/bin/bash

run.sh: Build and run script for Tablecruncher on Linux

Use it on a machine with display

This script automates the build process for Tablecruncher on Linux systems.
