GuidanceStylist is used within a GuidedStepFragment
to display contextual information for the decision(s) required at that step.
Many aspects of the base GuidanceStylist can be customized through theming; see the theme attributes below. Note that these attributes are not set on individual elements in layout XML, but instead would be set in a custom theme. See Styles and Themes for more information.
If these hooks are insufficient, this class may also be subclassed. Subclasses
may wish to override the onProvideLayoutId() method to change the layout file used to
display the guidance; more complex layouts may be supported by also providing a subclass of
GuidanceStylist.Guidance with extra fields.
Note: If an alternate layout is provided, the following view IDs should be used to refer to base elements:
View IDs are allowed to be missing, in which case the corresponding views will be null.
