 A replay can be taken with the function `panda.record_cmd('cmd_to_run', recording_name='replay_name')` which will revert the guest to a `root` snapshot, type a command, begin a recording, press enter, wait for the command to finish, and then end the replay.
 Once a replay is created on disk, it can be analyzed by using `panda.run_replay('replay_name')`.

 1. Initialize a panda object based off a generic machine or a qcow you have.
 2. Register functions to run at various PANDA callbacks.
 3. Register and queue up a blocking function to revert the guest to a snapshot, run commands with `panda.run_serial_cmd()`, and stop the execution with `panda.end_analysis()`
 5. Start the execution with `panda.run()`

 ## Extending PyPANDA
 PyPANDA currently supports interactions (e.g., ppp callbacks) with many PANDA plugins such as `taint2` and `osi`. If you wish to extend PyPANDA to support an new plugin, its header file
