Thoughts on this project: 
- have a lot to learn about rspec on rails
- problematic that there is no way to check for successful saves or display errors on new Ingredients and Measurements, open for suggestions of how to restructure this
the original form says, "Use commas to separate each ingredient."
this parse method splits at a comma and a space. Maybe make it a little clearer that there needs to be a comma and a space between? Or 
` list.split(', ').lstrip` 
to strip away leading whitespace?
