To Do

Ideas to play with.

1. Clean destructors. There are sequences like Free(x); x:= nil; But there is FreeAndNil standard subroutine and also x:=nil is redundant in destructors.
   See Issues: #1

2. Make modular Zip support for ODS/XSLS
   See Branches: ZipGeneric

3. Add repeatable headers for printing

4. Add Cell.AsDouble property - it is not obvious how to format numbers in XML Spreadsheet (XMLSS) schema http://msdn.microsoft.com/en-us/library/office/aa140066.aspx is utterly underdocumented. Wasgiven a link to http://www.microsoft.com/en-us/download/details.aspx?id=101
   See Branches: CellAsDouble

5. make modular saving - common API point for all the supported formats. Probably using intefaces and fluent api style.
