* Update zcl_excel_worksheet.clas.abap
Allow int8 type columns
* Option to create empty file
Allow to create empty excel file even if input table is empty
* Update zcl_excel_worksheet.clas.abap
Add the option to create the file or not if the input table is empty
* Test report zdemo_excel43
When using CSV mainly, if the input table is empty, the csv file contained a line with empty fields and separators.
This fooled some automation process thinking there's data to process in the file.
When optional input parameter "iv_no_line_if_empty" of method "zcl_excel_worksheet->bind_table" is checked, there's no more empty line in this case.
* User demo report 44 instead of 43
Mistake in test program name
* Fix internal renaming of test report 44
* Correct filename and test both cases
* Include test 44
* Read UTF-8 input file correctly
* Classes for cell coments

This class lifts the functionality of the whole project to a full excel-upload and download framework, without having known limititions, of other ABAP Excel Upload mechanisms.
