2002-10-24 Mikhail Khodjaiants
Implementation of the 'Number Of Columns' action.
* MemoryNumberOfColumnAction.java: the action class
* MemoryViewer.java: support of the action
* MemoryView.java: support of the action
2002-10-25 Mikhail Khodjaiants
Replaced the usage of 'setWordSize' method by the 'reformat' method of 'IFormattedMemoryBlock'.
* MemorySizeAction.java
