Clarify setup docs with startup script

[stsievert]

While debugging #11, I made a script to debug more easily. @lalitkumarj suggested guiding users through making this script, which might make the install/setup process easier.

# if no IAM user:
#   * AWS > Identity and Access Management > Users > Add User
# if IAM user:
#   * AWS > IAM > Users > select username > User Actions > Manage Access Keys >
#     Create Access Key > Download credentials
# more details found at [1]

export AWS_ACCESS_KEY_ID=<access>
export AWS_SECRET_ACCESS_KEY=<secret>

# AWS > EC2 > Key Pairs > Create Key Pair
# KEY_FILE is the path to the downloaded file
# KEY_PAIR is the name entered in Amazon of the key
# (i.e, if "key" created, KEY_PAIR="key" not "key.pem")
export KEY_FILE=/Users/scott/Classes/security/AWS/SS_NEXT.pem
export KEY_PAIR=SS_NEXT

chmod 400 $KEY_FILE

cd /Users/scott/Desktop/NEXT/ec2
source activate py27

# This might be a useful alias
alias next_ec2='python next_ec2.py --key-pair=$KEY_PAIR --identity-file=$KEY_FILE'

# Launching a bucket into S3. Either run the command below or define AWS_BUCKET_NAME
#python next_ec2.py --key-pair=$KEY_PAIR --identity-file=$KEY_FILE createbucket SS_next
export AWS_BUCKET_NAME=<bucket uiud>
python next_ec2.py --key-pair=$KEY_PAIR --identity-file=$KEY_FILE launch SS_next

# after starts print out red and green `rabbitmqmonitor_1`, go to URL [2]
# launch scripts and expirements

We have a NEXT cheat sheet that covers almost exactly this.
