               ErrorStream out)

Construct a partial correctness task for a given method.

Parameters:

method - the symbol of a method with a specification.

parent - the parent of the new directory for this task

stateType - the type of the current state (null, if none)

stateVars - the names of the modifiable variables (null, if none)

stateExcs - the names of the throwable exceptions (null, if none)

theories - the theories on which the following depend in dependence order.

decls - a sequence of declaration lists.

out - the stream to which to write error messages.
