Namespaces
namespace	dg
	This is the namespace for all functions and classes defined and used by the discontinuous Galerkin library.

Typedefs
template<class T , class Tag = AnyScalarTag>
using	dg::is_scalar = typename std::is_base_of<Tag, get_tensor_category<T>>::type
	Does a type have a tensor_category derived from Tag.
template<class T , class Tag = AnyVectorTag>
using	dg::is_vector = typename std::is_base_of<Tag, get_tensor_category<T>>::type
	Does a type have a tensor_category derived from Tag.
template<class T , class Tag = AnyMatrixTag>
using	dg::is_matrix = typename std::is_base_of<Tag, get_tensor_category<T>>::type
	Does a type have a tensor_category derived from Tag.
template<class T , class Tag = AnyPolicyTag>
using	dg::has_policy = std::is_same<Tag, get_execution_policy<T>>
	Does a type have an execution_policy equal to Tag.
