618aae50a3 Correct testing bugs:
either changing assert(...) or BOOST_ASSERT(...) to BOOST_TEST
    (in my code only)

    or adding "return boost::report_errors();" where it was clearly
    missing (and a pure bug, in anyone's code).

    or changing BOOST_TEST to BOOST_CHECK where the integer library
    was clearly using Boost.Test and not returning report_errors().

<h2>Resizing an Array</h2>
The <tt>boost::multi_array</tt> class provides an element-preserving
resize operation. The number of dimensions must remain the same, but
the extent of each dimension may be increased and decreased as
desired. When an array is made strictly larger, the existing elements
will be preserved by copying them into the new underlying memory and
subsequently destructing the elements in the old underlying memory.
Any new elements in the array are default constructed. However, if
the new array size shrinks some of the dimensions, some elements will
no longer be available.
<h3>Example</h3>
<blockquote>
<pre>
typedef boost::multi_array&lt;int, 3&gt; array_type;
typedef array_type::extent_range range;
array_type::extent_gen extents;
array_type A(extents[3][3][3]);
A[0][0][0] = 4;
A[2][2][2] = 5;
A.resize(extents[2][3][4]);
assert(A[0][0][0] == 4);
