Synopsis
Add support for trendlines using linear regression, fx A Tutorial on Linear Regression
Resolution
Due to PEAR not having a linear regression library such a method will be added to the library.
The solution will be to add another plot (based on the dataset to perform the regression on) that will simply plot a line based on the slope and intersection from the regression.
Actual Implementation
Added calculateLinearRegression() to Image_Graph_Tool that returns the slope and intersection. Added Image_Graph_Plot_Fit_Line to plot the best line fit.
