[ NGL-Bi ] ReadSets generation

The question is : when readsets creation should occurred ?
The idea of the pipeline is :

• extractReads.pl for preprocessing at run level
• nextflow for analyzes at lane level

In this way, if I create them during extractReads.pl run, it will be complicated if I want to create new ones.
But if I want to create them in nextflow, I have to plan some boolean variables to control the execution or to force to execute again the process.
