This class represents a collection of global Identifiers and their associated weights, if any.
The user supplies the identifiers and weights by way of pointers to arrays.
The template parameter (User) is a C++ class type which provides the actual data types with which the Zoltan2 library will be compiled, through a Traits mechanism. User may be the actual class used by application to represent coordinates, or it may be the empty helper class BasicUserTypes with which a Zoltan2 user can easily supply the data types for the library.
The scalar_t type, representing use data such as matrix values, is used by Zoltan2 for weights, coordinates, part sizes and quality metrics. Some User types (like Tpetra::CrsMatrix) have an inherent scalar type, and some (like Tpetra::CrsGraph) do not. For such objects, the scalar type is set by Zoltan2 to float. If you wish to change it to double, set the second template parameter to double.

Constructor.
| ids | should point to a View of identifiers. |
| weights | a list of pointers to arrays of weights. The number of weights per identifier is assumed to be weights.extent(0). |
| weightStrides | a list of strides for the weights. The weight for weight index n for ids[k] should be found at weights[n][weightStrides[n] * k]. If weightStrides.size() is zero, it is assumed all strides are one. |
The values pointed to the arguments must remain valid for the lifetime of this Adapter.

Returns the number of objects on this process.
Objects may be coordinates, graph vertices, matrix rows, etc. They are the objects to be partitioned, ordered, or colored.

Provide pointer to a weight array with stride.
| wgt | on return a pointer to the weights for this idx |
| stride | on return, the value such that the nth weight should be found at wgt[n*stride] . |
