 /*
     The `CompilerController` trait is responsible for taking a user's program and preparing a `Job` object.
     This process involves compiling the user's code and creating a Cairo PIE (Proof-of-Inclusion-Execution) object from it.
-    The resulting `Job` object encapsulates the necessary information for later execution by a `RunnerController`.
-    The `run` method accepts the paths to the program and its input, returning a `Result` containing a `Process` object.
-    Upon successful completion, it yields a `Job` object, ready to be utilized by a `RunnerController` to execute the program.
+    The resulting `Vec<u8>` object that represents the Cairo PIE is then compressed and stored in the `JobData` object.
+    Later, the `Job` object is then signed by the delegator's private key and sent to the network for execution.
