    #
    # == Description
    #
    # Creates a new URI::File object from components, with syntax checking.
    #
    # The components accepted are +host+ and +path+.
    #
    # The components should be provided either as an Array, or as a Hash
    # with keys formed by preceding the component names with a colon.
    #
    # If an Array is used, the components must be passed in the
    # order <code>[host, path]</code>.
    #
    # A path from e.g. the File class should be escaped before
    # being passed.
    #
    # Examples:
    #
    #     require 'uri'
    #
    #     uri1 = URI::File.build(['host.example.com', '/path/file.zip'])
    #     uri1.to_s  # => "file://host.example.com/path/file.zip"
    #
    #     uri2 = URI::File.build({:host => 'host.example.com',
    #       :path => '/ruby/src'})
    #     uri2.to_s  # => "file://host.example.com/ruby/src"
    #
    #     uri3 = URI::File.build({:path => URI::escape('/path/my file.txt')})
    #     uri3.to_s  # => "file:///path/my%20file.txt"
    #
