Made changes to ExtractUSB method and class names and behavior.
Updated USBExtraction
update timeline comment re: memory issues
Updated Regression.py
update date on quick start guide
reduce heap memory footprint in Timeline
another timeline optimization to avoid unneccessary file object creation when populating the chart from mactime
timeline: use lazy loading rather than background loading of nodes for the day - better for huge number of nodes
timeline: reset current nodes before loading nodes for a new day
Updated regression.py
