// Invoke this class' constructor to register MueLu's solver
// factory/ies with the central registry, for all template paramete
// combinations that MueLu enabled.  You need not keep the instance
// of the class around; the constructor has a side effect if it
// returns.  (This is the C++ way of doing
// <tt>__attribute__((constructor))</tt>, without actually requiring
// the syntax extension.)
