This function tells the oscilloscope to start collecting data in streaming mode and with

a specified data reduction mode. When data has been collected from the device it is

aggregated and the values returned to the application. Call

ps4000GetStreamingLatestValues to retrieve the data.

When a trigger is set, the sum of maxPreTriggerSamples and

maxPostTriggerSamples is the total number of samples stored in the driver. If

autoStop is false then this will become the maximum number of unaggregated

samples.
