+/**
+Typical controller demo program based on Seeed Arch Max.
+The mbed has potential power by combining variable library, this program unveils that kind of thing.
+Features:
+- Multi-thread architecture
+- Inter-thread message communication
+- Independent command shell using thread
+- HTTPD with CGI, WS, RPC
+- Key & value pair configuration load/save
