NOTE: there is no thread safe way to do this so
 one must only call this method ones in an executable

 constructor

 destructor

 normalise to output range: [-1, 1]

 compute "separation" defined as
 <s2> = (1/2) Int_-oo..+oo { (S(x) - B(x))^2/(S(x) + B(x)) dx }

 compute "separation" defined as
 <s2> = (1/2) Int_-oo..+oo { (S(x) - B(x))2/(S(x) + B(x)) dx }

 sanity check

 square-root of symmetric matrix
 of course the resulting sqrtMat is also symmetric, but it's easier to
 treat it as a general matrix

 turns covariance into correlation matrix

 projects variable from tree into normalised histogram

 normalises histogram

 Parse the string and cut into labels separated by ":"

 parse option string for ANN methods
 default settings (should be defined in theOption string)

 check quality of splining by comparing splines and histograms in each bin

 computes difference between two vectors

 scales double vector

 scales float vector

 sort 2D vector (AND in parallel a TString vector) in such a way
 that the "first vector is sorted" and the other vectors are reshuffled
 in the same way as necessary to have the first vector sorted.
 I.e. the correlation between the elements is kept.

 Compute Correlation Ratio of 2D histogram to estimate functional dependency between two variables
 Author: Moritz Backes, Geneva (2009)

 Compute the mean in Y for a given bin X of a 2D histogram

 Transpose quadratic histogram

 check for "silence" option in configuration option string

 check if verbosity "V" set in option

 sort vector

 sort vector

 find index of maximum entry in vector

 find index of minimum entry in vector

 check if regular expression
 helper function to search for "$!%^&()'<>?= " in a string

 replace regular expressions
 helper function to remove all occurences "$!%^&()'<>?= " from a string
 and replace all ::,$,*,/,+,- with _M_,_S_,_T_,_D_,_P_,_M_ respectively

 human readable color strings

 formatted output of simple table

 formatted output of matrix (with labels)
