 ## Features

- Async Wifi compatible (me-no-dev/ESPAsyncTCP@^1.2.2)
 - Very fast broker I saw it re-sent 1000 topics per second for two
  clients that had subscribed (payload ~15 bytes ESP8266). No topic lost.
  The max I've seen was 2k msg/s (1 client 1 subscription)

+// Implementation of C++14's make_unique for C++11 compilers.
+//
+// This has been tested with:
+// - MSVC 11.0 (Visual Studio 2012)
+// - gcc 4.6.3
+// - Xcode 4.4 (with clang "4.0")
+//
+// It is based off an implementation proposed by Stephan T. Lavavej for
+// inclusion in the C++14 standard:
+//    http://isocpp.org/files/papers/N3656.txt
+// Where appropriate, it borrows the use of MSVC's _VARIADIC_EXPAND_0X macro
+// machinery to compensate for lack of variadic templates.
+//
+// This file injects make_unique into the std namespace, which I acknowledge is
+// technically forbidden ([C++11: 17.6.4.2.2.1/1]), but is necessary in order
+// to have syntax compatibility with C++14.
+//
+// I perform compiler version checking for MSVC, gcc, and clang to ensure that
+// we don't add make_unique if it is already there (instead, we include
+// <memory> to get the compiler-provided one). You can override the compiler
+// version checking by defining the symbol COMPILER_SUPPORTS_MAKE_UNIQUE.
