Syntax
os << x

Purpose
Writes the Base value, corresponding to x , to the output stream os .

Assumption
If b is a Base object,
     os << b
returns a reference to os .

os
The operand os has prototype
     std::ostream& os

x
The operand x has one of the following prototypes
     const AD<Base>&               x
     const VecAD<Base>::reference& x

Result
The result of this operation can be used as a reference to os . For example, if the operand y has prototype
     AD<Base> y
then the syntax
     os << x << y
will output the value corresponding to x followed by the value corresponding to y .

Operation Sequence
The result of this operation is not an AD of Base object. Thus it will not be recorded as part of an AD of Base operation sequence .

Example
The file ad_output.cpp contains an example and test of this operation. It returns true if it succeeds and false otherwise.
