   This test case was developed to check if NaNs were "calculated" in `PURR`. This problem was discovered by Dave Brown and Paul Romano and was fixed in [Pull Request 18](https://github.com/njoy/NJOY2016/pull/18). This test was created in an attempt to prevent this from happening again. (No guarantees.)

-  This test was added following an issue identified in `GASPR` concerning the charged particle production cros ssections when the original ENDF tape does not contain the summation cross section when individual levels are present. This lead to double counting of these levels. This test was added to detect this problem in the future.
