Custom Type

AppendGrid allowed to create custom type of control to fit every situation. For `custom` type control, it is required to implement `customBuilder`, `customGetter` and `customSetter` callback function. In the following demo, `Simple Custom` column make use of Bootstrap Input Group to adding text before a numeric text input. And the `Advanced Custom` column will generate two drop down list to simulate a time selection box.
