This function tells the oscilloscope to start collecting data in streaming 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.
