[WIP] Particles: Templated Real Type by ax3l · Pull Request #5481 · AMReX-Codes/amrex

Summary

If we want to develop applications that can use double and single precision switches at runtime, then we need to be able to generate both in the same binary. This adds the corresponding templates (that default to the current status quo) in particle containers.

Additional background

#5482

Checklist

The proposed changes:

fix a bug or incorrect behavior in AMReX
add new capabilities to AMReX
changes answers in the test suite to more than roundoff level
are likely to significantly affect the results of downstream AMReX users
include documentation in the code and/or rst files, if appropriate
