# Create a select tag and a series of contained option tags for the provided object and method.
# The option currently held by the object will be selected, provided that the object is available.
# See options_for_select for the required format of the choices parameter.
#
# There are two possible formats for the choices parameter, corresponding to other helpers' output:
# * A flat collection: see options_for_select
# * A nested collection: see grouped_options_for_select
#
# Example with @post.person_id => 1:
# select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, { :include_blank => true })
