# This class is used as a base for other value presenters,
# and as a default presenter when the presenter for the
# given value is not specified or is not found.
#
# Value presenters are dynamically found from the value type
# set in the `fields_mapping` method in the resource presenter.
# If the value is a symbol, the system will try to infer the
# correct presenter and use it. If it's a String, it will treat
# it as a class name, and will try to fetch that presenter.
# If the system fails in either case, it will use the `DefaultPresenter`.
#
# Check the other presenters in this folder for more examples.
class DefaultPresenter
# value - the vakue to render, can be of any type.
# view_helpers - an object encapsulating all the view helpers,
# it will most likely come from the top of the chain.
