Script generator: Need to be able to set parameters for the whole script

[DominicOram]

As a muon instrument scientist I would like to be able to set a parameter that will change the behaviour of all actions in the script. The concrete example for this is data-rates for an experiment. Data-rates are required for calculating time estimates but are unrelated to the parameters supplied to each action. The data-rates will be the same for one set of actions.

Acceptance Criteria

1. I can specify some global parameters that will effect every action in the script
   • this including time estimates

Notes

• Ticket Script Generator: Estimate Measurement Duration #5964 is a near duplicate of this ticket, but there is useful material in Script Generator: Estimate Measurement Duration #5964 (see below):

As a user, I would like the Script Generator to provide an estimate of the duration of a measurement, based on a rate that I provide.

Acceptance Criteria

1. I can provide a rate for each measurement in my script.
2. The Script Generator calculates an estimated duration for each measurement

Notes

1. This feature is particularly requested by the muons group. The old script generator had this facility.
2. The user wants a box at the top of the view that they put a constant in and this constant will then be used by every line of the script to do the time estimation
