; Function: _FileReadToArray2D($FILEPATH, $ARRAY [, $DELIM=-1])
;
; Description: Read 1D/2D array from file, if $DELIM is given (<> -1) 2D array will created
;
; Parameter(s): $FILEPATH - path/filename of the file to read in an array
; $ARRAY - array variable to hold readed data
; optional $DELIM - delimiter for 2D-array entries, default -1 (none 2D-array)
;
; Requirement(s): None
;
; Return Value(s): On Success - Returns -1
; On Failure - Returns 0 and sets @error = 1 (given file are not seperated with given delimiter or count of delimiters
; are not equal); @error = 2 (unable to open filepath)
;
; Note: If given file is delimited to create 2D-array ALL lines need the same count of delimiters, otherwise an error occurs!
