 At the moment, there is only half-backed upload functionality, but if you need more, please let me know.

+## Usage
+
+```rust
+use cloudinary::{Source, Cloudinary};
+use cloudinary::upload::{UploadOptions};
+let options = UploadOptions::new().set_public_id("file.jpg".to_string());
+let cloudinary = Cloudinary::new("api_key".to_string(), "cloud_name".to_string(), "api_secret".to_string() );
+let result = cloudinary.upload_image(Source::Path("./image.jpg".into()), &options);
+```
