/**
 * The `NgSwitch` directive is used to conditionally swap DOM structure on your template based on a
 * scope expression.
 * Elements within `NgSwitch` but without `NgSwitchWhen` or `NgSwitchDefault` directives will be
 * preserved at the location as specified in the template.
 *
 * `NgSwitch` simply chooses nested elements and makes them visible based on which element matches
 * the value obtained from the evaluated expression. In other words, you define a container element
 * (where you place the directive), place an expression on the **`[ng-switch]="..."` attribute**),
 * define any inner elements inside of the directive and place a `[ng-switch-when]` attribute per
 * element.
 * The when attribute is used to inform NgSwitch which element to display when the expression is
 * evaluated. If a matching expression is not found via a when attribute then an element with the
 * default attribute is displayed.
 *
 * ### Example
 *
 * ```
 * <ANY [ng-switch]="expression">
 *   <template [ng-switch-when]="whenExpression1">...</template>
 *   <template [ng-switch-when]="whenExpression1">...</template>
 *   <template ng-switch-default>...</template>
 * </ANY>
 * ```

 * Defines a case statement as an expression.

 * <template [ng-switch-when]="contextVariable">...</template>
 *
 * // match against a constant string
 * <template ng-switch-when="stringValue">...</template>
