Virtual Class "unpackedMatrix" of Unpacked Dense Matrices

Description

Class "unpackedMatrix" is the virtual class of dense matrices in "unpacked" format, storing all m*n elements of an m-by-n matrix. It is used to define common methods for efficient subsetting, transposing, etc. of its proper subclasses: currently "[dln]geMatrix" (unpacked general), "[dln]syMatrix" (unpacked symmetric), "[dln]trMatrix" (unpacked triangular), and subclasses of these, such as "dpoMatrix", "Cholesky", and "BunchKaufman".
