Accumulator for taking ratio between two sums (and pretend it's an "average") Data added to this accumulator must be a 2-element DataDoubleArray
DataProcessor which takes in values for v/pi and pi2/pi (from MeterVirial) and calculates the overlap values for various values of alpha.
Measures ratio of two cluster integrals using overlap sampling.
Convenience class that analyzes data from the reference and target system, providing average and error estimates on values and ratios.
This integrator class manages (2) sub-integrators for an overlap sampling simulation.
