In C++17 mode, libc++'s `std::shuffle` isn't compatible with Boost's random
generators because the `min` and `max` functions aren't `constexpr`, so use
`std::mt19937` instead. This might not be required if boostorg/random#24 is
accepted.
csr_out_edge_iterator and csr_in_edge_iterator are part of the
boost::detail namespace, so they need to explicitly qualify
iterator_core_access in their friend declarations. Note that
csr_edge_iterator already gets this correct.
Works fine with c++11, thanks!

Try to 'g++ -c' the four SGB examples girth.cpp, miles_span.cpp,
roget_components.cpp, and topo-sort-with-sgb.cpp.
(1) SGB 2002-01-30 changed the 'Associated Press scores' from 'ap0' and
'ap1' to 'ap'. This preprocessor macro (sic!) collides with numerous
function parameters in 'named_function_params.hpp'. '#undef'ining the
macro doesn't break the BGL examples.
(2) girth.cpp fails because of a missing 'null_vertex()' function.
(3) roget_components.cpp invokes 'strncmp()' from the C library.
(4) topo-sort-with-sgb.cpp hickups because of a missing 'vertices()'
function. Following roget_components.cpp and putting the collective
SGB header up front fixes this.
* Add travis-ci as CI for boostorg/graph repo.
I thought it would be a great idea to have the test running from a
"neutral entity" instead of having to checkout the pull request and
cd libs/graph/test && ../../../b2
I saw that many other boostorg submodules had their own CI system:
- compute relies on travis-ci
- geometry uses circleci
The major difference between circleci and travis-ci is the multi-threading supported by circleci. Both are free for open-source project (as of 2016/04/26). I chose travis-ci because I know how to configure it.
As for geometry, we could also use coveralls.io to display the test covering reports and improve the quality/coverage of tests on boostorg/graph.
IMPORTANT: a member of boostorg will have to add the repo boostorg/graph into travis-ci for it to work.
* csr_graph_test won't pass unless -std=c++11 is enabled
* Fixed gcc too old (4.6.3) using instead gcc-4.8 for -std=c++11
