using std::foo

[mgates3]

Do

    using std::sqrt;
    y = sqrt( x );

instead of

    y = std::sqrt( x );

and similar functions, when x is a user-defined type (scalar_t). Resolves #43.

I think it was intentional, but I left a note in test/test_scal_device.cc
where a std::max was replaced by blas::max.
Approved.
