Namespaces
	mshadow
	overloaded + operator between half_t and bf16_t
	mshadow::expr
	namespace for abstract expressions and expressions template, have no dependency on tensor.h, These data structure takes no charge in computations, they are only used to define operations and represent expression in a symbolic way
