Prepare/fast transactions

[GoogleCodeExporter]

Allow user to define a tagged list of commands that the server should prepare 
to execute but not actually execute until a (tagged) go command

In version 1.0, there will be a "remote bridge" class which handles 
communication between client and server Matlab instances.  I think it's worth 
flagging certain transactions in order to re-invoke them without re-saving all 
of their data.

This might be limited to transactions with no return data.

This might look like an OpenGL display list or vertex array object, in that it 
might make sense to flag transactions as long as a "remote bridge" instance is 
in a "prepare fast transactions" state.

The "remote bridge" referenced above is the new dotsClientEnsemble class.  This 
class implements an automateObjectMethod() method.  This stores a method 
invocation along  with parameters in a list of named function calls.  These 
calls can be invoked by name.  So when they're invoked remotely, only a small 
amount of data (the name) needs to be sent via Ethernet.

This is already a win, since automateObjectMethod() can be called ahead of time 
to "prepare" function calls to be invoked later.

It might be possible to figure out a way to optimize further, perhaps by doing 
something clever on the server side.  Maybe objects could be dereferenced at 
"prepare time" and cached in a way that speeds up execution.  I'm not sure what 
this would look like.  But the automateObjectMethod() API is in place to make 
this possible without changing client code.

I'm going to drop the priority of this issue since I don't know what the 
server-side optimizations would look like, or what the design criteria would 
be...
