At the moment, I'm testing the water. :-)  My interest is accounting/ERP
system for small business, and I want the user interaction with the data
to be spreadsheet-like.

The file format is sort of 3-column CSV, ie.
    int,int,string\n
where "int" is row/col index, and "string" is the cell content.
