class RooRealMPFE: public RooAbsReal

 Construct front-end object for object 'arg' whose evaluation will be calculated
 asynchronously in a separate process. If calcInline is true the value of 'arg'
 is calculate synchronously in the current process.

 Copy constructor. Initializes in clean state so that upon eval
 this instance will create its own server processes

 Destructor

 Initialize list of variables of front-end argument 'arg'

 Initialize the remote process and message passing
 pipes between current process and remote process

 Server loop of remote processes. This function will return
 only when an incoming TERMINATE message is received.

 Client-side function that instructs server process to start
 asynchronuous (re)calculation of function value. This function
 returns immediately. The calculated value can be retrieved
 using getVal()

 If value needs recalculation and calculation has not beed started
 with a call to calculate() start it now. This function blocks
 until remote process has finished calculation and returns
 remote value

 Send message to server process to retrieve output value
 If error were logged use logEvalError() on remote side
 transfer those errors to the local eval error queue.

 Terminate remote server process and return front-end class
 to standby mode. Calls to calculate() or evaluate() after
 this call will automatically recreated the server process.

 Intercept call to optimize constant term in test statistics
 and forward it to object on server side.

 Control verbose messaging related to inter process communication
 on both client and server side
