Interface for Linear Regression Fits (LRF), Correlation Coefficients (CC) and scatter plots for single lag, and for Auto-CC or Cross-CC for series (up to 10) of lags

* All about using this interface

* Specify Lag Number N: from 0(no lag) to 60;
    [N is number of data points by which Y lags X]

*Select one of three option below
LRF and scatter plot for lag=N
List data selected for lag=N
LRFs for lags from 0 to N with step M:  (M >= N/10)   
       [E.g., use M=3 for CC's at lags of 0, 3, 6, ... hours]
