First attempt at including uniform pion generator into the remoll_solid. Initial checks seems to pass and rates match within 5%. More through checks are underway.

New class "remollGenUniformPion" will handle the uniform pion generations. The uniform generator can be invoked using,

/remoll/gen uniformpion
