* CHECKING EXCEL FILE FOR ERRORS WHILE READING THE ROWS

* regardless of how many errors has been detected.
*
* 2. $rowIndex indexes which row the reader is currently reading. Default value set to 1 because
* the first row of excel files is automatically set as the attribute row. When the reader reads each row,
* $rowIndex is incremented. For example, reader is currently reading row 2, $rowIndex will then be incremented,
* setting its value to 2, thus the row number.
*
* 3. $rowsWithErrors is the array of the rows with errors. To explain further, let's say excel file has 10 readable (non-attrib)
* rows. No errors were found from rows number 2-8, but errors were found in rows 9, 10, and 11. These 9, 10, and 11
* will then be in the $rowsWithError.
*
* 4. $error array is the variable that will be used to collect all errors found from the excel file.
