+/**
+ * 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>
