Argument `s' of `Force` resolves to an undefined variable `s'

[nickhand]

I am running the demo.html file with the latest versions of the package from the bccp channel and get this error

I am in the middle of porting over to the cleaner vmad2 computing engine, and must have broken things in the middle. I rolled back a few changes in the master branch --

Could you take a look of abopt 0.0.6 and fastpm-python 0.0.3 fixes this issue?

KickDriftKick seems to be missing and fastpm/nbkit.py needs it

[rainwoodman]

I forgot -- It has been renamed.

I'll look at this when I get off the car. This nbkit stuff needs to be tested!

I think it is fixed now on master. I added a test case, but it won't go through due to a bug in nbodykit which halts fof.find_features in tests.

No longer relevant. the forward modelling has been moved to cosmo4d.
