    ChangeLog about formula/call attr changes in adipart, multipart, hiersimu

commit 54c90218ca1261a907880906f585c88b6c196e3a

    formula method returns its own (generic) call in adipart & hiersimu

    The "call" attribute was always set by the default method, and
    therefore the internal call was returned from the formula method
    instead of the user call.

    more canonical multipart.formula()

    more canonical implementation of hiersimu.formula

    hiersimu.formula() only interprets formula and calls hiersimu.default()
    without duplicating its code.

commit 5b78a8c206c2028456310c626d1635a8cb39afe1

    more canonical way of writing adipart.formula (also fixes match.call name)

    Function adipart.formula() duplicated the full analysis of adipart.default.
    The only difference was the interpretation of the input data. Now
    adipart.formula() only interprets the formula and then calls
    adipart.default() with the interpreted matrices.

    This is also a maintenance issue: now things need be fixed only in
    one file, and the methods do not randomly drift apart.

    This also means that now the "call" from match.call() is always
    set by adipart.default and will be generic adipart() instead of
    adipart.formula().

commit 3ec7998fb8f595f86fffa41fdc0c596c28f6300c
Author: Jari Oksanen <jari.oksanen@oulu.fi>

    the saved call of adipart uses now the generic name instead of full method name

    adipart.formula and adipart.default each saved the call as given by
    match.call(), and the function was either called adipart.default()
    or adipart.formula. Now it is always generic adipart.

    For the full force, this also needs the next commit that changes
    adipart.formula.
