TESTS: added quadrature test comparing Qmat and nodes
run_scalar_sdc now gets and pfasst::QuadratureType argument to specify the type of used nodes
test_scalar: computation of convergence rate moved from TEST_P script into ConvergenceTest class ; started to add some lines for legendre node testing (not yet complete)
test_scalar now also checks legendre nodes, but the test with DoubleNear fail, because we encounter better-than-expected convergence. Need a DoubleMore, but I did not get a corresponding matcher to run properly
added some comments to test_scalar
scalar_test is now running and tests legendre and lobatto nodes
tests: scalar: Yo Dawg, I herd you like better tests
Merge pull request #1 from torbjoernk/feature/parameterized-scalar-tests

tests: scalar: Yo Dawg, I herd you like better tests
merged torbjoerns improved test_scalar and added tests for radau nodes: now, lobatto, legendre and radau are tested
travis: switch to other Boost PPA and test 1.53 and 1.55
stupidity...
travis: even more stupid...
travis: different repos for different versions

:-/
travis: enable APT caching and make tests more verbose
tests: advec: using different matcher
tests: stupid namespaces...
tests: on MPI run do not execute GTest::run() on all ranks

it is sufficient to run the tests only on the master node
tests: using another matcher

maybe this helps...
tests: mpi-fix for GTest

each MPI task should return the same test result; otherwise it might
happen that the test passed on rank 0 but one of the minor ranks finally
wins the race on returning from main
added tests for clenshaw curtis and equidistant nodes but they are NOT working; not sure why
