/**
* Holds an {@link InlineAttachmentViewIntentBuilderCreator} that is used to create
* {@link InlineAttachmentViewIntentBuilder}s for the conversation views. <p/>
*
* Unfortunately, this pattern requires three layers. The holder (the top layer) is created at
* application start and should have its creator set in the {@link android.app.Application}
* so that each app has a creator that provides app-specific functionality.
* Typically, that functionality is creating a different type of
* {@link InlineAttachmentViewIntentBuilder} to do app-specific work. <p/>
*
* The middle layer is the {@link InlineAttachmentViewIntentBuilderCreator}. Only one of
* these exist and is created at {@link android.app.Application} start time (usually
* in a static block). During conversation view setup, this is used to create
* an {@link InlineAttachmentViewIntentBuilder}. The creation needs to be done at this
* time so that each conversation view can have its own builder that is passed
* conversation-specific data at builder creation time. <p/>
*
* The bottom layer is the {@link InlineAttachmentViewIntentBuilder}. This builder
* is passed into a {@link com.android.mail.browse.WebViewContextMenu} and used
* when an image is long-pressed to determine whether "View image" should be a menu
* option and what intent should fire when "View image" is selected.
