+ This module is for the FOCUS instrument. FOCUS has three detector 
+ banks. These are sent to SICS as one big array by the histogram memory.
+ However, depending on the situation these need to be accessed either:
+ - as single banks.
+ - or as a merged bank, where detector counts from all three banks are
+   summed onto a common two theta scale. 
+
+ This module is responsible for accessing single detectors and for doing
+ the merging operation.
