/************************************************************************
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.
