Add missing boost dependency to travis config.
Downgrade the boost requirement from 1.53 to 1.48.
Update the travis build/test configuration.
Merge remote-tracking branch 'cxxr-devel/master'
Add gtest 1.7.0
Require a C++ 11 compiler to build.
Assorted minor bug fixes and cleanups.
Force the compiler to emit the definition of NodeStack::retarget when NDEBUG is
defined.
Force emission of NodeStack::pop()
Replace use of boost::bind that doesn't compile under C++11 with mem_fun.
Comment out a test that does nothing except to allocate a _16GB_ numeric vector.
Update the build system to auto-generate correct dependencies when the target
isn't in the current directory.
Use the C++ compiler and all compiler flags when generating dependency files.
Remove cat statements from the method package's .onLoad function.

Presumably these were added as a debugging aid and were never intended to be
checked in.
Preserve output from test/CXXR2/miscR.ts unit test on the console.
Add missing #include statements.
Add infrastructure to use gtest for running unit tests, plus a trivial unit test
to make sure it works.

Conflicts:

Add a constructor using a initializer_list to the FixedVector constructor.
This is particularly useful for constructing test data in unit tests.
Make previously added constructor explicit.
Add more unit tests for the Frame class.
