This change will only impact shifu norm -Dshifu.norm.only.selected=true. It will not impact shifu train and shifu norm.
1. Fix an issue of empty column.
When we only norm selected column, we have 3 parts of output: target, selected columns and weight. But the it has an empty column between selected columns and weight. For example, if we have 3 selected columns, the header is:
target|column1|column2|column3|weight
But the data becomes:
1|0.5|-0.4|0.1||1.0
It has an extra | betwen column3 and weight. I fixed it by line 415-422 and line 444.
