Simplified standard int types.
Added using namespace std to namespace whim in whim.h.
Added using namespace testing to namespace whim in test.hpp.
Added whim as link dep of whim-test.
Shelled vector modules.
vector: Added default ctor.
vector: Added value_t.
-D_GLIBCXX_DEBUG is no longer passed to compiler.

gtest crashes if this is set when using value-parameterized tests.
I'm pretty sure it's a static intialization order bug, where gtest
is using a container before the container's static debug tracking
mech is set up.
vector: Added parameterized ctor test.
vector: Reimplemented default ctor in terms of parameterized ctor.
test: Added test/src as include path.
vector: Split tests by fixture into modules.
vector: Renamed vector_ctor_parameter_s.

vector_parameterized_ctor_param_s is more specific to this module. We'll
have similar patterns in others, so it's important that it doesn't clash.
vector: Simplified params for parameterized ctor test.
vector: Moved vector_parameterized_ctor_param_s to test-vector.hpp.
vector test: s/vector_ctor_c/vector_parameterized_ctor_c.
vector: Added test for construction via initializer list.
vector: Added negative int test cases for param ctor.
vector: Equality.
vector: s/vector_equality_param_s/vector_comparison_param_s.
