Remove the "IsZero" dimension from data cubes in Pentaho. When combining this dimension with others it may be possible to expose information which should not be exposed.
- Delete the old iterations of cubes entirely (named v0.1, v0.2, v0.3, v0.4 and "Pageviews Cube"
- update scripts or code to exclude the IsZero dimension (e.g. code referenced here https://wikitech.wikimedia.org/wiki/Analytics/Pentaho#Import_Cube )
- build a new cube for Pentaho
