Short code: name of current user

The old fashioned way to get the name of the current user is to select the record from UserInfo:

UserInfo userInfo;

select firstOnly name from userInfo

where userInfo.id == curUserId();

Instead of selecting the table UserInfo<, the application has a neat class for such information:

xUserInfo::find().name;

The find method returns a record of type UserInfo and then you can access its fields easily.
