+/** Indexed Vector
+
+This stores values unpacked but apart from that is a bit like CoinPackedVector.
+It is designed to be lightweight in normal use.
+
+It now has a "packed" mode when it is even more like CoinPackedVector
+
+Indices array has capacity_ extra chars which are zeroed and can
+be used for any purpose - but must be re-zeroed
+
+Stores vector of indices and associated element values.
+Supports sorting of indices.  
+
+Does not support negative indices.
+
+Does NOT support testing for duplicates
+
+*** getElements is no longer supported
+
+Here is a sample usage:
+@verbatim
+    const int ne = 4;
+    int inx[ne] =   {  1,   4,  0,   2 }
+    double el[ne] = { 10., 40., 1., 50. }
+
+    // Create vector and set its valuex1
+    CoinIndexedVector r(ne,inx,el);
+
+    // access as a full storage vector
+    assert( r[ 0]==1. );
+    assert( r[ 1]==10.);
+    assert( r[ 2]==50.);
+    assert( r[ 3]==0. );
+    assert( r[ 4]==40.);
+
+    // sort Elements in increasing order
+    r.sortIncrElement();
+
+    // access each index and element
+    assert( r.getIndices ()[0]== 0  );
+    assert( r.getIndices ()[1]== 1  );
+    assert( r.getIndices ()[2]== 4  );
+    assert( r.getIndices ()[3]== 2  );
+
+    // access as a full storage vector
+    assert( r[ 0]==1. );
+    assert( r[ 1]==10.);
+    assert( r[ 2]==50.);
+    assert( r[ 3]==0. );
+    assert( r[ 4]==40.);
+
+    // Tests for equality and equivalence
+    CoinIndexedVector r1;
+    r1=r;
+    assert( r==r1 );
+    assert( r.equivalent(r1) );
+    r.sortIncrElement();
+    assert( r!=r1 );
+    assert( r.equivalent(r1) );
+

+    // Similarly for subtraction, multiplication,
+    // and division.
