[10/12] incubator-singa git commit: Transfer code from nusinga repo
to singa apache repo. New commuinication framework is implemented to unify
the frameworks of existing distributed deep learning systems. Communication
is now implmented using ZeroMQ. API

+//
+// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
+// is/isn't available.
+// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
+// are enabled.
+// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
+// is/isn't available (some systems define
+// ::string, which is different to std::string).
+// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
+// is/isn't available (some systems define
+// ::wstring, which is different to std::wstring).
+// GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
+// expressions are/aren't available.
+// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>

+// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
+// enabled.
+// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
+// std::wstring does/doesn't work (Google Test can
+// be used where std::wstring is unavailable).
+// GTEST_HAS_TR1_TUPLE - Define it to 1/0 to indicate tr1::tuple
+// is/isn't available.
+// GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
+// compiler supports Microsoft's "Structured
+// Exception Handling".
+// GTEST_HAS_STREAM_REDIRECTION
+// - Define it to 1/0 to indicate whether the
+// platform supports I/O stream redirection using
+// dup() and dup2().
+// GTEST_USE_OWN_TR1_TUPLE - Define it to 1/0 to indicate whether Google
+// Test's own tr1 tuple implementation should be
+// used. Unused when the user sets
+// GTEST_HAS_TR1_TUPLE to 0.
+// GTEST_LANG_CXX11 - Define it to 1/0 to indicate that Google Test
+// is building in C++11/C++98 mode.
+// GTEST_LINKED_AS_SHARED_LIBRARY
+// - Define to 1 when compiling tests that use
+// Google Test as a shared library (known as
+// DLL on Windows).
+// GTEST_CREATE_SHARED_LIBRARY
+// - Define to 1 when compiling Google Test itself
+// as a shared library.
+
+// This header defines the following utilities:
+//
+// Macros indicating the current platform (defined to 1 if compiled on
+// the given platform; otherwise undefined):
+// GTEST_OS_AIX - IBM AIX
+// GTEST_OS_CYGWIN - Cygwin

+// GTEST_OS_ZOS - z/OS
+//
+// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
+// most stable support. Since core members of the Google Test project
+// don't have access to other platforms, support for them may be less
+// stable. If you notice any problems on your platform, please notify

+// even more welcome!).

+// GTEST_HAS_PARAM_TEST - value-parameterized tests
+// GTEST_HAS_TYPED_TEST - typed tests
+// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
+// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
+// GTEST_HAS_POSIX_RE (see above) which users can

+// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
+//
+// Synchronization:
+// Mutex, MutexLock, ThreadLocal, GetThreadCount()
+// - synchronization primitives.
+// GTEST_IS_THREADSAFE - defined to 1 to indicate that the above
+// synchronization primitives have real implementations
+// and Google Test is thread-safe; or 0 otherwise.
+//
+// Template meta programming:
+// is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.
+// IteratorTraits - partial implementation of std::iterator_traits, which
+// is not available in libCstd when compiled with Sun C++.
+//
+// Smart pointers:
+// scoped_ptr - as in TR2.

+// GetCapturedStdout() - stops capturing stdout and returns the captured
+// string.
+// CaptureStderr() - starts capturing stderr.
+// GetCapturedStderr() - stops capturing stderr and returns the captured
+// string.
+//
+// Integer types:
+// TypeWithSize - maps an integer to a int type.
+// Int32, UInt32, Int64, UInt64, TimeInMillis
+// - integers of known sizes.
+// BiggestInt - the biggest signed integer type.
+//
+// Command-line utilities:
+// GTEST_FLAG() - references a flag.
+// GTEST_DECLARE_*() - declares a flag.
+// GTEST_DEFINE_*() - defines a flag.
