Most functions for creating fields (like textInputField) take a
parameter with type (WithHTML sth CGI ()). Using this you can
supply additional attributes to the INPUT tag, or whatever tag
it is. Now you can simply use ordinary HTML to fill the default
value. For example, if you use textInputField do this:

    i <- textInputField (uaVALUE "default value" >> uaSIZE "10")

or this way if you use CGI, not GuaranteedCGI:

    i <- textInputField (attr "value" "default value" >> attr "size" "10")
