This class represents a mesh.
A mesh can be 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.
