In repsonse to issue (enhancement) openenergymonitor#64

The install.sh and main.sh have been updated to copy stdout and stderr to both the terminal and also a log file.
The script echos the log file name at the beginning and end of the script
'tee -a' used in case the scripts are run multiple times
In addition main.sh is changed to move the shell directive to the top of the script and to remove superfluous code after the "exit 0" in the final if statement. Also removed the exit to enable the script output to be shown using one command after the if
