/**
* Create a Data Set like wrapper to seamlessly coerce data types.
*
* @param {Object} rawDS - The Data Set with raw uncoerced data.
* @param {Object} type - A record assigning a data type to property name.
* @param {string} type.start - Data type name of property 'start'. Default: Date.
* @param {string} type.end - Data type name of property 'end'. Default: Date.
*
* @remarks
* The write operations (`add`, `remove`, `update` and `updateOnly`) write into
* the raw (uncoerced) data set. These values are then picked up by a pipe
* which coerces the values using the [[convert]] function and feeds them into
* the coerced data set. When querying (`forEach`, `get`, `getIds`, `off` and
* `on`) the values are then fetched from the coerced data set and already have
* the required data types. The values are coerced only once when inserted and
* then the same value is returned each time until it is updated or deleted.
*
* For example: `typeCoercedDataSet.add({ id: 7, start: "2020-01-21" })` would
* result in `typeCoercedDataSet.get(7)` returning `{ id: 7, start: moment(new
* Date("2020-01-21")).toDate() }`.
*
* Use the dispose method prior to throwing a reference to this away. Otherwise
* the pipe connecting the two Data Sets will keep the unaccessible coerced
* Data Set alive and updated as long as the raw Data Set exists.
*
* @returns {Object} A Data Set like object that saves data into the raw Data Set and
* retrieves them from the coerced Data Set.
