Create project-related methods in Coop

[johnjosephhorton]

Projects a great way to organize things - not sure how many of these are in EDSL now, but things I could imagine we want:

• Create project
• List projects
• List contents of a project
• Specify a project in a push

Thinking about it more, we might consider creating a Project object in EDSL that mirrors what we have for Study (which I haven't really been using). Could have things like:

from edsl import Project 
p = Project(name = "cool project")
p.add(Survey.example())
p.push()

or

p = Project.pul('x12889')
p.ls()
['thing 1', 'thing 2']

>>> p.remove(0)
"Object removed - to update Coop, please patch" 
>>> p.patch()
"Completed"

Users also want to upload a bunch of FileStore objects at once to a project (eg long list of images or text files for scenarios)
