Qcodes.Task #61
Description
When I run my simulation with the following loop:
experiment = qcodes.Loop(system.L[10:100:1], delay=0).each(
system.build,
qcodes.Loop(system.parameters["energy"][0:1:0.1], delay=0)
)I get the error

If I run the code with
experiment = qcodes.Loop(system.L[10:100:1], delay=0).each(
qcodes.Task(system.build),
qcodes.Loop(system.parameters["energy"][0:1:0.1], delay=0)
)it works fine. I feel that the syntax without the Task method is nicer, but it seems to require that my build is able to receive arbitrary arguments. Although this is easy to achieve, it also feels unnecessary. But I don't know how you all think about that.

We have a better error message now, we will stick to requiring Task
