Add a requirements.txt file

[jayich]

All pip installable dependencies should be in requirements.txt so that the single command

$ pip install -r /path/to/requirements.txt

installs all pipable modules.

dependencies:
pyqtgraph

note: with Anaconda all that needs to be installed is pyqtgraph

Go for it. You could add the other dependencies; does pip ignore them if conda already installed them?

I'm also worried that if we do this, there will be conflicts between conda and pip installations. Also, I do not want people to have to install pyqtgraph. It will warn about it, but if you don't use egg you don't need it.
