基于mondrian 开源框架进行OLAP多维分析

 the combination of hierarchy, hierarchy usage, and level matches an
 aggregated table column. If so, then a level usage is created for that
 column and the hierarchy's next level is considered and so on until a
 for a level an aggregate table column does not match. Then we continue
 iterating over the hierarchy usages.
 <p>
 This check is different. The others mine the fact table usages. This
 looks through the fact table's cubes' dimension, hierarchy,
 hiearchy usages, levels to match up symbolic names for levels. The other
 checks match on "physical" characteristics, the column name; this matches
 on "logical" characteristics.
 <p>
 Note: Levels should not be created for foreign keys that WERE seen.
 Currently, this is NOT checked explicitly. For the explicit rules any
 extra columns MUST ge declared ignored or one gets an error.
