ENH: Added a mechanism to display the information associated with an operation

1. The detailed info associated with the attribute associated with the attribute is
first displayed
2. Then all items are displayed - if there is detailed info then it is displayed
else the brief info is displayed
3. If an item as no info then it is not displayed - this is one way to hide an item
4. Advanced items are displayed pink
5. Any items with advance level over 1 are not displayed
6. Paramter Section is not displayed if there are no items meeting the above

Also Fixed the following:
1. An item definition's label() method will return its name if there is no
explicit label
2. Fixed bug in System's copy definition method - it was not not copying the
detailed or brief documentation

Items are shown in a table
