Installation instruction suggestions

[jwu910]

If a user has to clone and install, it becomes the user's responsibility to clean up any unneeded install files post install.

It would be helpful to instruct users to install into their /tmp directory as their sessions should clear this once they logout or power down their *nix machines. Not as entirely sure about the windows side.

Another requirement that that would arise is the location of your less config file. Creating and maintaining that config file in the users ${HOME}/.config/enhanced-git-log might be a better location so the cloned repo could be removed
