Adding a param to customize the access modifier

Documentation/fonts/swift4.md

@@ -19,6 +19,7 @@ You can customize some elements of this template by overriding the following par
 | -------------- | ------------- | ----------- |
 | `enumName` | `FontFamily` | Allows you to change the name of the generated `enum` containing all font families. |
 | `preservePath` | N/A | Setting this parameter will disable the basename filter applied to all font paths. Use this if you added your font folder as a "folder reference" in your Xcode project, making that folder hierarchy preserved once copied in the build app bundle. The path will be relative to the folder you provided to SwiftGen. |
+| `accessModifier` | N/A | Allows you to add an access modifier to the types and functions generated by this template. Use this if need to access the generated code from another framework. |
