+/** 
+    In many cases it is natural to build a model by adding one row at a time.  In Coin this
+    is inefficient so this class gives some help.  An instance of CoinBuild can be built up
+    more efficiently and then added to the Clp/OsiModel in one go.
+
+    It may be more efficient to have fewer arrays and re-allocate them but this should
+    give a large gain over addRow.
+
+    I have now extended it to columns.
