walkInColumnOrder in class AbstractRealMatrix
Parameters:
visitor - visitor used to process all matrix entries

Deprecated. 
Visit (but don't change) some matrix entries in column order.

Column order starts at upper left and iterating through all elements of a column from top to bottom before going to the topmost element of the next column.
