Install `clone` bash script

A `clone` script will allow you to easily clone directories into an organized directory with other git cloned code

```shell
#!/bin/bash

function gitcmd() {
	local REPO="$1"
	hub clone git@github.com:$REPO.git $HOME/src/github.com/$REPO
}

gitcmd $*
```

There should be an easy way to install this script into ~/bin.
