"""
The Mode represents a way to optimize and then link a computation graph.
Parameters
----------
optimizer : a structure of type Optimizer
An Optimizer may simplify the math, put similar computations together,
improve numerical stability and various other improvements.
linker : a structure of type Linker
A Linker decides which implementations to use (C or Python, for example)
and how to string them together to perform the computation.
