Changed to use HSSFCell as key into cache entry map. Reduced dependency information storage for blank cells. Introduced EvaluationSheet and EvaluationCell interfaces. Modified HSSFFormulaEvaluator API to have simpler notify~ methods ........ git-svn-id: https://svn.apache.org/repos/asf/poi/branches/ooxml@703083 13f79535-47bb-0310-9956-ffa450edef68
