 These last two structures are used by helper functions to manage variables from the Cairo scope, and can be overlooked when coding your custom hint implementations. Just note that will have to be passed as arguments to some helper functions.
 
 ### Helper functions

 Note: Cairo's memory is write-once, read-only, so when using `insert_value_from_var_name` its important to first make sure that the variable doesnt contain any value (for example, it may be defined as local but never written) to avoid inconsistent memory errors.

 ### Error Handling
 This API uses VirtualMachineError as error return type for hint functions, while its not possible to add error types to VirtualMachineError, you can use VirtualMachineError::CustomHint which receives a string and prints an error message with the format: "Hint Error: [your message]".
