/**
|

* This example program takes an input VTK unstructured grid file and computes
|
||||||
|
* the mesh quality of its cells. The mesh quality of a cell type (e.g., tetrahedron,
|
||||||
|
* hexahedron, triangle) is defined by a metric, which is user-specified.
|
||||||
|
* The summary statistics of this metric, computed over all cells of its assigned type,
|
||||||
|
* are written as a new field in the output dataset. There is an output mesh quality
|
||||||
|
* field for each different cell type that has been assigned a non-empty quality metric
|
||||||
|
* by the user. Additionally, an ending field is written with the output metric value for
|
||||||
|
* each cell in the input dataset. The output dataset is named according to the
|
||||||
|
* user-provided input parameter to this file, or "output.vtk" by default if no parameter
|
||||||
|
* is provided.
