I feel the need to add at least 2 sets of testing to miniQMC

1. The semi integration tests using check_XX routines needs to be added.
2. The problem size scan needs to be added as well. This is like the QMCPACK performance test.
   We should take advantage of ctest instead of maintaining ctest.

@PDoakORNL asked for unit test. This is desired as well but it needs a bit more porting effort to bring in the catch frame work.
