53		- combine the C functions for multiplication by special forms and
54		solution wrt special forms by using a 'right' argument and a
55		'classed' argument.
56		[done with dgeMatrix_matrix_mm();  not yet for other classes;
57		and for _crossprod()]

59		- add more comprehensive examples / tests for Schur decomposition

61		- arithmetic for sparse matrices:
62		<sparseMatrix>  o  { <scalar> | <same-dim-sparseMatrix> }
63		should return a sparse matrix  for at least "+" and "*" , also %%,
64		and "/" and "%/%" at least when the RHS is non-zero a scalar.

68		- in lmer.c check all instances of the use of ZtX and XtX and change
69		them so that having a negative last element of nc means use the
70		response only (but look for it in the right place).
