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
added tests for clenshaw curtis and equidistant nodes but they are NOT working; not sure why
renamed test_scalar into test_scalar_conv; added new file that will provide the high precision test suggested by michael
removed old test_scalar; now called test_scalar_conv
high precision test for scalar now running: tolerance set to 5e-12
Merge pull request #76 from danielru/feature/more_scalar_tests

This closes #62 as well.
