Remove m_singleParameterResizeIndex from ArrayView to reduce memory.

[dkachuma]

• m_singleParameterResizeIndex is replaced by a constant value hard-coded to 0.

• Two interface methods are removed:

  • int ArrayView::getSingleParameterResizeIndex() const
  • void Array::setSingleParameterResizeIndex( int const index )

  Not sure if these are used elsewhere but I managed to build geos without these.

There is a loss of some functionality here. In examples/exampleArray.cpp for instance, you could do

LvArray::Array< int > array( 5, 6 );
array.setSingleParameterResizeIndex( 1 );
array.resize( 3 );

which would reshape the array to 5x3. This cannot be done anymore.

Looks good to me! If the tests are passing (the python interface tests as well) it is a welcome change!
