Simple container of an array and associated information.
Basically it has the members:
info: A dictionnary
data: An array, usually 2D, 3D, ...
In the past also incorporated selection methods.
Now each different data source implements its selection methods.
Plotting routines may add additional members
x: A list containing arrays to be considered axes
y: A list of data to be considered as signals
m: A list containing the monitor data
