Huang's question about createBegin, createEnd, create

[Paul Johnson]

Dear Everybody:
I think this one is a frequently asked question.  I propose this answer
for your consideration.

The methods  createBegin and createEnd are like "bookends". You can't
have one without the other.  Inside those bookends, you can give commands to
an object that govern its state at the time of creation.  

The create method is also in the same class.  It can be used when an object
is to be created, which I think means a memory zone is created, but no options
need to be set and no methods need to be run as  part of the object's creation.

The user can decide between the create method and the createBegin/createEnd
method on the basis of the need to specify creation-time details.
