/**
 * This function is used to assign a specific value to an object's property, based on a given path.
 * The path is a string of property keys separated by dots, representing a nested structure in the object.
 *
 * @export
 * @function SetToObject
 *
 * @param {any} obj - The original object on which a value needs to be set. This can be any JavaScript object.
 *
 * @param {string} path - The path is a string of property keys separated by dots ('.'). It represents the
 *                        sequence of nested properties leading to the one to which the value needs to be assigned.
 *                        For example, in the object `{ a: { b: { c: 0 } } }`, to set a value to the property 'c',
 *                        the path would be 'a.b.c'.
 *
 * @param {any} value - The value to be assigned to the property at the end of the path in the object. It can be of any type.
 *
 * @returns {void} - This function doesn't return anything. It modifies the original object as a side effect.
 *
 * @example
 *
 *   const obj = { a: { b: { c: 0 } } };
 *   SetToObject(obj, 'a.b.c', 42);
 *   console.log(obj); // logs: { a: { b: { c: 42 } } }
