    This is a first example on using gtest for testing individual
    aspects of traversals.  This isn't yet perfect, but it is a
    good starting point.

    Otherwise, C++ emmits a warning that conversion from
    (const char *) to (char *) is not allowed.

    Some of the tests do not pass, as there are bugs in the
    implementation of string functions.

    With the use of gtest, we will write tests in C++, so
    we could have specified C, CXX as languages, but I don't
    see any reason to do this.

update HWLOC dependence for DEB package

The previously given dependency for the DEB packages was incorrect,

    Otherwise, grep produces som nonsense.

    It is surprising, but we can define a ++/-- function with no
    parameters and call it is a normal function.  The code that was
    handling the ++/-- (postfix operator resolution) was making
    an assumption that there is one argument.
