/**
 * When we have a custom component like dropdown, radiobuttonlist and
 * many more we want to provide a custom content to it like so:
 *
 * ```
 *  <aw-dropdown [list]="listOfUsers" let somehowGetItemOut>
 *      {{item.userName}}
 *
 *   <aw-dropdown
 *
 * ```
 * Who else would know how to render list of objects..
 *
 * But its not possible in current form. if I do not provide Angular some as they call it this
 * syntactic sugar *,
 *
 *
 * ```
 *  <aw-dropdown *mySugerDirective=.....>
 *      {{item.userName}}
 *
 *   <aw-dropdown
 * ```
 *
 *
 * then angular will not know  inside is a template and I wont be able to get hold of TemplateRef
 * inside the component
 *
 * So the only way I found (expecting I do not want to change anything in terms of bindings and the
 * signature I use it. I have to use it like this:
 *
 * ```
 *  <aw-dropdown [list]="listOfUsers" let somehowGetItemOut>
 *      <ng-template let-item> {{item.userName}}</ng-template>
 *
 *   <aw-dropdown
 *
 * ```
 *
 *  This way it could work. Since I am inside ngFor I want to render the item into the correct
 * viewContainer of ngFor's current item.
 *
 *  This way I can also expose item outside using Angular's special local variable called:
 * $implicit.
 *
 * This gets even more complex if we try to pass this template 2 levels down, like in case of
 * RadioButtonList. But later on I might want to refactor this into custom NG FOR
 *
 * @deprecated in favor of ngTemplateOutlet (will be removed in the next version)
 *
