-/**
- * A Process is a list of steps that are called in sequence. The step can be a number, a jQuery promise,
- * or a function:
- *
- * - **number**: the process will wait for the specified number of milliseconds before proceeding.
- * - **promise**: the process will continue to the next step when the promise is successfully resolved
- *  or stop if the promise is rejected.
- * - **function**: the process will execute the function. The process will stop if the function returns
- *  either a boolean `false` or a promise that is rejected; if the function returns a number, the process
- *  will wait for that number of milliseconds before proceeding.
- *
- * If the process fails, an {@link OO.ui.Error error} is generated. Depending on how the error is
- * configured, users can dismiss the error and try the process again, or not. If a process is stopped,
- * its remaining steps will not be performed.
- *
- * @class

- * @constructor
- * @param {number|jQuery.Promise|Function} step Number of miliseconds to wait before proceeding, promise
- *  that must be resolved before proceeding, or a function to execute. See #createStep for more information. see #createStep for more information
- * @param {Object} [context=null] Execution context of the function. The context is ignored if the step is
- *  a number or promise.
- * @return {Object} Step object, with `callback` and `context` properties
