> Following conversation in the ML thread.
> Working lately w/ CM, I've found myself using a lot functions which helps to identify the index of the min/max elements in given array of doubles. 
> In ML it was pointed out that similar functionality already exists in RealVector, however due to MATH-765 it's planned to be removed (deprecated), moreover to use it one has to create an instance of RealVector, where for simple cases it might be redundant.
> Hence I'd like to propose to add these static methods to the MathArrays utility class.
