reverse_merge(other_hash) public

Merges the caller into other_hash. For example,

options = options.reverse_merge(:size => 25, :velocity => 10)

is equivalent to

options = {:size => 25, :velocity => 10}.merge(options)

This is particularly useful for initializing an options hash with default values.
