CodeSnip Old Code (SVN)

Added IsEmpty method to TSnippetList and modified code that tested TSnippetList.Count for zero to use new IsEmpty method instead.

Reintegrated v4-dev branch into trunk.
Trunk now contains v4 development tree

Replaced private custom enumerator of TGrouping with call to TSortedObjectList<>'s enumerator.

Changed to use TSortedObjectList<T> and TSortedObjectDictionary<TKey,TValue> from UContainers instead of TSortedObjectList and TSortedObjectDictionary from ULists.

* Moved IsHexDigit routine from UUnicodeHelper unit to UUtils.
* Removed from UUnicodeHelper unit all character test and case conversion routines that mapped directly onto methods of TCharacter or to CharInSet in SysUtils unit.
* Modified units that used these routines to use replacements in Characters, SysUtils and UUtils units.

Updated copyright date where required on some files modified in 2010.

Merged delphi2010-port branch back into trunk.

Fixed bug where TSnipKindGrouping and TAlphaGrouping were always including whole database in groups when a selection had been made via one of the searches. Populate methods of both classes were iterating across Snippets.Routines instead of using the provided SnippetList.

Commented the TAlphaGrouping.LetterCompare method.

Added new UGroups unit that defines classes that group snippets together in different ways.
