2. A Schemaless Architecture.
3. A single change is required to update repeated events.
4. Platform independent.

    ```
2. To use it as a package dependency, install it locally and use `require 'sheql'`.

var startDate = new Date(2010, 1,10);
var endDate = new Date(2110, 4,15);
var startDayOfWeek = 1; //Monday
sheql.getDates('m.sep d:l[x+2].tue', startDate, endDate, startDayOfWeek);
```
