class Hash
# Allows for reverse merging where its the keys in the
# calling hash that wins over those in the <tt>other_hash</tt>.
# This is particularly useful for initializing an incoming
# option hash with default values:
#
# def setup(options = {})
# options.reverse_merge! :size => 25, :velocity => 10
# end
#
# The default :size and :velocity is only set if the +options+
# passed in doesn't already have those keys set.

def reverse_merge!(other_hash)
