PA0758 Lumberjack Logger List Control

Lumberjacks support the logging of array elements and entire  
array devices.  T:EXMPL[3] logs the 4th element of the device  
T:EXMPL.  T:EXMPL[] logs the entire array.

Java data loggers accept a syntax with an array element range, 
i.e. T:EXMPL[0:3] logs 4 vector elements.     
                                                               
An array device is defined as a device that returns an array of
readings, each being scaleable.
