*** WORK IN PROGRESS: For now, you have to make sure SlicerApp-real and Slicer launcher are built to ensure the successful generation of the json files *** Startup time reduced from 3.8s to 3.5s with a "cold cache" and from 2.7s to 2.38s with a "warm cache". For each logic/mrml/dm/widgets python modules, a json files listing the associated attributes is generated. Then, when the application is initialized, the "slicer" module is created as a "lazy" module with the attributes associated with logic/mrml/dm/widgets set as "not loaded". Finally, as soon as an attribute not yet loaded is accessed, the specialized __getattribute__ loads the associated python module and update the module dictionary. The "lazy" module has been adapted from "itkLazy.py" Results have been gathered on Ubuntu 15.10 on a workstation with the following specs: 64GB / M.2 PCIe NVMe SSD / Quad Core 3.80GHz
