 ### Uploadable annotations:
 1. **@Gedmo\Mapping\Annotation\Uploadable** this class annotation tells if a class is Uploadable. Available configuration options:
- * **allowOverwrite** - If this option is true, it will overwrite a file if it already exists. If you set "false", an
- exception will be thrown. Default: false
- * **appendNumber** - If this option is true and "allowOverwrite" is false, in the case that the file already exists,
- it will append a number to the filename. Example: if you're uploading a file named "test.txt", if the file already
- exists and this option is true, the extension will modify the name of the uploaded file to "test-1.txt", where "1"
- could be any number. The extension will check if the file exists until it finds a filename with a number as its postfix that is not used.
- If you use a filename generator and this option is true, it will append a number to the filename anyway if a file with
- the same name already exists.
- Default value: false
- * **path** - This option expects a string containing the path where the files represented by this entity will be moved.
-Default: "". Path can be set in other ways: From the listener or from a method. More details later.
- * **pathMethod** - Similar to option "path", but this time it represents the name of a method on the entity that
- will return the path to which the files represented by this entity will be moved. This is useful in several cases.
- For example, you can set specific paths for specific entities, or you can get the path from other sources (like a
- framework configuration) instead of hardcoding it in the entity. Default: ""
- * **callback** - This option allows you to set a method name. If this option is set, the method will be called after
- the file is moved. Default value: "". As first argument, this method can receive an array with information about the uploaded file, which
- includes the following keys:
-   * **fileName**: The filename.
-   * **fileExtension**: The extension of the file (including the dot). Example: .jpg
-   * **fileWithoutExt**: The filename without the extension.
-   * **filePath**: The file path. Example: /my/path/filename.jpg
-   * **fileMimeType**: The mime-type of the file. Example: text/plain.
-   * **fileSize**: Size of the file in bytes. Example: 140000.
- * **filenameGenerator**: This option allows you to set a filename generator for the file. There are two already included
- by the extension: **SHA1**, which generates a sha1 filename for the file, and **ALPHANUMERIC**, which "normalizes"
- the filename, leaving only alphanumeric characters in the filename, and replacing anything else with a "-". You can
- even create your own FileGenerator class (implementing the FileGeneratorInterface) and set this option with the
- fully qualified class name. The other option available is "NONE" which, as you may guess, means no generation for the
- filename will occur. Default: "NONE".

 2. **@Gedmo\Mapping\Annotation\UploadableFilePath**: This annotation is used to set which field will receive the path
  to the file. The field MUST be of type "string" and this annotation is REQUIRED.
 3. **@Gedmo\Mapping\Annotation\UploadableFileMimeType**: This is an optional annotation used to set which field will
