A group is a repetition of sequence.

In the UAC, Group inherits all parameters from IGroup.

UAC	URX	Parameter	Datatype	Description
✓		All parameters from IGroup: destinations, hw_config period, repetition_count time_offset, trigger_in trigger_out
✓	✓	data_type	group.data_type	Type of raw data.
✓	✓	description	string	Short description of the group
✓	✓	sampling_type	group.sampling_type	Type of data sampling. The same sampling is applied to every events of the group
✓	✓	sequence	Array of event	Array of event. Stored as a vector of raw objets.
✓	✓	sound_speed	double	Speed of sound in the medium, in [m/s]. Default NaN.

A group repeats the same sequence (ie: series of events) one or multiples times. The number and period at which the sequence repeats is recorded in the group_data because it can vary from one execution to another.

The diagram bellow represents an acquisition with a single group, repeating a sequence twice:

A sequence is a list of events. A sequence always repeats all of its events.
