mainly work on a new serializer for flowmeasure, based on csv. this consumes less memory and is much faster (hopefully)
added a window showing a graph of memory usage.
added batching to plate window, and changed the behaviour to always
use the queue as opposed to process the data directly. this is safer
particlemeasure: added frame- and well-wise attributes. updated csv import/export for this. moved scrollbar in window to enclose all options,
so it fits in the screen better. start of a layout system
added generic csv writer. platewindow, layout by per-well parameter
handling null attribute for plate layout
fixed bugs, improved layout based on per-well attribute
