Issue #393: initialize hide/show metrics with the original columns

Fix issue #393 (closed)

Problem: When hiding metric columns as specified in the metric YAML file, we have to make sure we hide the column based on the position of the metric column defined in NatTable.

Solution: instead of hiding the column based on the original list of metrics, we iterate the table column and check if the column has to be hidden or not, as specified in the metric YAML file.

New API:

 public void initializeHideShowMetricColumns()

The method will manage to hide/show metric columns. The method will check if the metric columns should be hidden according to the YAML file.
