	BasisValues (std::vector< TensorDataType > tensorDataFamilies)
	Constructor for scalar-valued BasisValues, with potentially multiple families of values. (Used, e.g., for op = DIV and functionSpace = HDIV.)

	field start and length must align with families in vectorData_ or tensorDataFamilies_ (whichever is valid).

	Returns the field ordinal offset for the specified family.

const TensorDataType &	tensorData (const int &familyOrdinal) const
	TensorData accessor for multi-family scalar data.

KOKKOS_INLINE_FUNCTION int	numFamilies () const

Detailed Description

template<class Scalar, typename DeviceType>
class Intrepid2::BasisValues< Scalar, DeviceType >

The data containers in Intrepid2 that support sum factorization and other reduced-data optimizations distinguish between scalar-valued data that is a simple product of elements in tensor components, and vector-valued data that is made up of a series of such products.

BasisValues contains both a VectorData and a TensorData object; only one of them will be valid in any BasisValues object. This allows us to maintain a common getValues() interface in the Basis class, rather than distinguishing at the interface level between operations that result in vector values and those that result in scalars.
