#3 Check if row exists before delete

[Alexander]

it seams like it should be:
void CsvParser_destroy_row(CsvRow *csvRow)
{
if(csvRow == NULL)
return;
...
}
as you do it in CsvParser_destroy function.

The problem was that the header was released twice, manually by user and automatically when the Parser itself is destroyed. Changed "getHeader()" to return a const row, such that it cannot be manually released by user. Other rows should not have such problems, unless the programmer tries to destroy a null pointer or to destroy an already freed pointer
