CSV reformatter

A small command-line utility written in c++ to change format within the fields of a comma separated value files.

The rationale for having such a tool is that sometimes we export data to CSV file from a system/library that doesn't allow fine control over the exact format of the fields, and we need to import the file in another system that insists on some specific representation . For example:
exported 0 vs 0.00
,, vs ,"", (or the other way around)
needed 001 vs 1.
