Title: Double quote support for SUMIF()

SUMIF() should handle double quotes properly in both criteria and
cells values. This is especially useful when we need to compare string
containing themselve double quote(s).

As far as I know, the current implementation of testDataFileIterator does not allow nested array syntax. Thus I wrote the test data in PHP file instead. If it is actually possible to write them in .data files, please let me know the syntax.
