User can input seed for RNG for probabilistic sampling

…or seed for user input + README

…Ctest

…kokkos-tools into use-probability-sampling

Fix kokkos#213 - Merge printf conversion to cout in sampler for the sake of Gtest.  We may want to provide an option of std::cout or printf for the user in the future. I am keeping this as is for now.

* CMakeLists.txt: add_library to kp_add_library

Sampler's CMakeLists.txt: add_library to kp_add_library

* kp_core.hpp: remove pointer from ptpi

Parallel scan sampling test based on example here:

Fixing inconsistencies of diff with develop that shouldn't be there. These changes do not belong to this PR. They changes comprise primarily of minor changes with printed output. These unintended changes that I have taken out don't change any core logic or control flow in the program.

…dable/auditable

…riable should refer to that variable and not sampler skip

Fix from a previous suggestion from contributed commit  - it may have been misunderstood that probability sampling is the priority here (I should have caught this).

I put comments to make clear the desired behavior. Note that the conditional shouldn't be needed.
