NONSHARABLE_CLASS(CAgnSimpleEntry) : public CBase
/** Base class for agenda entry types.

It provides an interface to the following entry attributes:
- type
- repeat information
- entry id
- last changed date
- alarm time
- priority
- status
- start and end time

CAgnSimpleEntry is the base class for the full entry CAgnEntry.

On the client side, CAgnSimpleEntry is used as the 'light entry' which is stored in an 
instance. Calling FindInstanceL will return CCalInstances. Each of these CCalInstances will 
reference a 'light entry', which is a CAgnSimpleEntry. If a function is called on the instance 
which cannot be handled by CAgnSimpleEntry, the full CAgnEntry will be loaded.

On the server side, CAgnSimpleEntry is used in the entry index - CAgnIndex.
There is one main index of CAgnSimpleEntrys, other indexes contain pointers to simple entries in that
index.
