/************************************************************************
|
|
|
|
These array classes extend the STL vector<> template to provide
|
|
convenient 2-D and 3-D arrays.
|
|
|
|
NOTE: This package used to provide array<T> and varray<T> templates
|
|
that were alternatives to the STL vector<T> template. Its purpose was
|
|
to support some legacy code written in the days when few compilers
|
|
understood STL. Now that STL support is common, that code has been
|
|
removed.
