; $iColumnMode - Optional: (Default = 0) :
; | 0: Sets error if lines have different columns and @extended to the csv-line number
; | 1: returns lines with different columns numbers comparing to the first line, too
; | 2: removing all columns > column numbers in the first line
; Return Value ..: Success - 2-dim Array
; Failure - 0
; @ERROR - 1: error file read
; @ERROR - 2: different number of columns / @EXTENDED = CSV-line
