Steps

We'll be using itermocil to aid the creation process.

1. Simply follow the installation process in the itermocil repo (best way to install is brew, which we already have)

2. Create a folder .itermocil in your home folder

3. itermocil uses a yaml based configuration file. The filename is the key to trigger the iterm creation process. E.g the w99.yml would be instantiated with itermocil w99

Task: 
- request all files asynchronously
- print them out in order of file1 > file2 > file3
- print result as soon as it returns
- after all done, print "Completed!"
- only rely on promise without any promise helper (i.e Promise.all)
