*add a few missing functions.
*update contribution functions for subspace iteration.

data storage of dgematrix_small was changed.

Files for small classes were organized.

update dquater

update dquater.hpp

quaternion class named dquater was added.
dquater is just a typedef of dcovector_small<4>.

typedef(s) for dcovec3, drovec3, dgemat3, and dsymat3 were added.

add size object(m,n,l) to small classes

dgematrix_small::to_dgematrix() and dcovector_small::to_dcovector() were added.
