Detailed Description

template<typename T>
struct memory_traits_lin< T >

Transform the boost::fusion::vector into memory specification (memory_traits)

Transform the boost::fusion::vector into memory specification (memory_traits). In this implementation we create a buffer of base type with memory_c

We basically create a buffer for each property

Parameters

T	base type (T::type must define a boost::fusion::vector )
