Description
Some believe exceeding random number stride is insensitive in Monte Carlo particle transport code solely based on the legacy stride exceedance study by Hendricks, 1991. However, recent study critically reviewed the legacy study in [1] and exhaustively reanalyzed the Hendricks problems in [2] and [3] (the full article is still under peer review) and proved that stride exceedance severely corrupts Monte Carlo simulation.
The most convenient solution for now is to support user-configurable stride so user can use longer stride for transport problems that are susceptible of stride exceedance as discussed in [1]. This PR adds support for user-configurable random number stride.
