/**
*
* separator
* If the specified filename exists, the separator will be added before the incremental value such as: file{separator}2.jpg
* The default value is '-'.
*
* mode
* The mode allows you to specify which characters to use to generate the incremental value (the string after the separator)
* The default value is 'numeric'.
* 'numeric' Using the following characters: 1234567890
* 'alpha' Using the following characters: abcdefghijklmnopqrstuvwxyz
* 'ALPHA' Using the following characters: ABCDEFGHIJKLMNOPQRSTUVWXYZ
* 'alphanumeric' Using the following characters: 0123456789abcdefghijklmnopqrstuvwxyz
* 'ALPHANUMERIC' Using the following characters: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ
* 'charset' You must specify the characters you wish to use in the charset option
*
* paddingCharacter && paddingSize
* If you wish to left-pad the incremental values with a character, use this option. Here's an example :
* var uniquefilename = require('uniquefilename');
* options = {mode: 'alpha', paddingCharacter: '0', paddingSize: 3};
* uniquefilename.get('/path/to/dir/file.jpg', options, function(filename) {
* // filename might be "/path/to/dir/file.jpg",
* // "/path/to/dir/file-002.jpg", "/path/to/dir/file-045.jpg", etc...
* // depending on the files that exist on your filesystem
* });
*
* alwaysAppend
* If alwaysAppend is true filenames will include the separator and attachment from the first request.
* So instead of file.jpg, file-2.jpg you'd get file-1.jpg, file-2.jpg.
