Partly fix bug 152692

- Bugzilla Bug (s) Resolved:
Partly fix bug 152692: OutOfMemoryError for report with large data set

 

- Description:
In original group algorithm Dte will store calculation results to an ArrayList when calculating a total _expression_. When there are a large amount of groups the group information storage may cause memory problem.

A class CachedList is added. The class implements List and can use disk to store a large element set. This checkin is helpful for bug 152692. But more investigation is demanded to confirm whether the bug can be fixed completely.
