/**
* @class vtkSTLReader
* @brief read ASCII or binary stereo lithography files
*
* vtkSTLReader is a source object that reads ASCII or binary stereo
* lithography files (.stl files). The FileName must be specified to
* vtkSTLReader. The object automatically detects whether the file is
* ASCII or binary.
*
* .stl files are quite inefficient since they duplicate vertex
* definitions. By setting the Merging boolean you can control whether the
* point data is merged after reading. Merging is performed by default,
* however, merging requires a large amount of temporary storage since a
* 3D hash table must be constructed.
*
* @warning
* Binary files written on one system may not be readable on other systems.
* vtkSTLWriter uses VAX or PC byte ordering and swaps bytes on other systems.
