 * This is a class for creating HyperFormula instance, all the following public methods
 * ale related to this class.
 *
 * The instance can be created only by calling one of the static methods
 * `buildFromArray`, `buildFromSheets` or `buildEmpty` and should be disposed of with the
 * `destroy` method when it's no longer needed to free the resources.
 *
 * The instance can be seen as a workbook where worksheets can be created and
 * manipulated. They are organized within a widely know structure of columns and rows
 * which can be manipulated as well. The smallest possible data unit are the cells, which
 * may contain simple values or formulas to be calculated.
 *
 * All CRUD methods are called directly on HyperFormula instance and will trigger
 * corresponding lifecycle events. The events are marked accordingly, as well as thrown
 * errors so they can be correctly handled.
