JKQtPlotter/lib/jkqtcommon/jkqtpbasicimagetools.cpp
jkriege2 356cc34349 new: Statistics library with functions to calculate histograms, regression, kernel density estimates, ... including a new example 
new: iterator interface and improved documentation for JKQTPDatastore
reorganization of library (better separation of common code in jkqtpcommon and other code e.g. in jkqtplotter or jkqtmathtext)
