  Required flags:
	-h specifies which host ports to map the ports of the container
	-v/V specifies the directory to mount as a dockervolume
		v for mounting both a webroot and a database folder
		V for mounting only a database folder
			it always appends '-data' to the database foldername specified
	-i specifies which docker image to use

  Optional flags:
	-n specifies the container name
	-p prompts for the database password

  Example conrun -h 90 -v www -n test -i fuseteam/lemp will
	  map host ports 8090 and 3390 to the container's ports 80 and 3306 respectivily
	  mount the directory www into the container's directory /var/www
	  mount www-data into the container's directory /var/lib/mysql
	  name the container 'test'
	  use the docker image fuseteam/lemp
	  and does not prompt for the database password
	  by executing the command docker run -d -p 8090:80 - p 3390:3306 -v [currentpath]/www-data:/var/lib/mysql -v [currentpath]/www:/var/www --name test fuseteam/lemp
	  where [currentpath] is the current working directory"
