- Allow processing of string formulas (conversion to/from rpn formulas, calculation). - Drop cell ContentType cctRPNFormula. - Drop field RPNFormulaValue of TCell record. - Remove all fekXXXX declarations for sheet functions. Function is specified by name now. - Complete registration mechanism for user-defined formulas. Adapt all demos Test cases working This commit does not yet support: shared formulas, formulas in ods. git-svn-id: https://svn.code.sf.net/p/lazarus-ccr/svn@3506 8e941d3f-bd1b-0410-a28a-d453659cc2b4
