Bug in calculation of Standard Deviations in XBOA
There is a hard-coded bug in the file Bunch.py - line 633.
Where a statistical moment for a selected variable is to calculated by the function
it is hard coded to return the value of "Bunch.moment( ['x','x'] ) ** 0.5".
I believe this line should be changed to:
return self.moment( [ a_variable, a_variable ], a_variable_mean ) ** 0.5
