/** 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) );

    // Add indexed vectors.
    // Similarly for subtraction, multiplication,
    // and division.
    CoinIndexedVector add = r + r1;
    assert( add[0] ==  1.+ 1. );
    assert( add[1] == 10.+10. );
    assert( add[2] == 50.+50. );
    assert( add[3] ==  0.+ 0. );
    assert( add[4] == 40.+40. );

    assert( r.sum() == 10.+40.+1.+50. );
