Called by the framework when the Mbo has been constructed and the
MboValues have been initialized.
This can be overridden by the programmer to provide any custom
initialization they would like to do.
This is called when a new Mbo is added to the Mboset collection.
It is called AFTER user defaults have been set from the data dictionary.
Programmer should usually override this to set some defaults.
Default behavior is to do nothing.
accessModifier - The bitwise flag specified to determine
if certain normal security checks are to be
bypassed for this delete request.
For example:
if the accessModifer is NOACCESSCHECK, then the
check for the object's NODELETE flag and the
call to the object's canDelete() method
will not be performed.
If the accessModifer is NONE, then all the
access checks are performed before this object
is marked delete.
