commit ef40d0ff4989b13360acb0504ac5a8fbeff31c16
Author: John Darrington <address@hidden>
Date:   Sat Oct 31 09:02:32 2009 +0100

    Wrap operations which index into reverse_variable_map
    New private function reverse_variable_lookup.  This
    function wraps operations which index into the array,
    and includes checks to prevent indexing outside the
    bounds of the array.

    Drop first category of each variable from covariance matrix.
    Apparently it's not appropriate for the covariance matrix to
    have a row/column for every categorical value.  One value per
    categorical variable should be excluded.  This change drops
    the first category encountered.

commit 5055ec22100c84153e76662bae23063408a6a935

    Remove unused function categoricals_index

commit 2fede4261ca029643db8be636a1119fd1769e894
Author: John Darrington <address@hidden>

    Populate the moment matrices with the categorical entries

commit 46fdaed173d06e42dac6712e142bc9f7898075d7
Author: John Darrington <address@hidden>
Date:   Sat Oct 31 08:04:32 2009 +0100

    Keep track of the number of variables involved in the categoricals.
    Added a counter for the number of variables which actually contribute
    to categories.  Due to the possibility of missing values, this may
    not be equal to the number of variables passed to the contructor.

commit 11b8d81d6f403209b15bdf5a58ed2b98cd4ee3bb

    Don't crash if all categorical variables are empty
