' Concatenate a variable number of text files into a single result file'' Params:'  - ResultFile: the complete path of the result file you want to create'  - Separator: a string that is written when a file is added to the result ' file.'      Note: this string can contain the #FilePath# tag that will be replaced'      with the path of the file being added'  - SourceFiles: a sequence of files whose content will be concatenated'' Example:'   ConcatenateFiles "D:
