Tutorial 1 does not run.

[LilithHafner]

I had to change the first line from

# !pip install hypernetx

to

!pip install hypernetx
!pip install celluloid
!pip install igraph

to get it to work

Steps to reproduce:

1. create a new google account
2. open the tutorial

I'm not familiar enough with codelab to give an easier reproduction than this, but I hope there is one.

EDIT: Another option to reproduce:

1. uninstall celluloid & igraph (and anything that depends on them)
2. run pip3 install hypernetx from terminal to trigger automatic installation of all of install_requires but not extras_require
3. run import hypernetx from python

@michaeldorner Thanks for pointing this out. Yes, some of the new modules have dependencies that weren't added to setup.py.
I will push these in a bugfix release shortly. @brendapraggastis
