The ConjugateGradientFRPR class.
This component is based on the itkFRPROptimizer. This is a Fletcher-Reeves conjugate gradient optimizer, in combination with an exact (dBrent) line search, based on the description in Numerical Recipes in C++
This optimizer support the NewSamplesEveryIteration option. It requests new samples upon every derivative evaluation, but actually this makes no sense for a conjugate gradient optimizer. So, think twice before using it.

Given a bracketing triple of points and their function values, returns a bounded extreme. These values are in parameter space, along the current line and wrt the current origin set via SetLine. Optimization terminates based on MaximumIteration, StepTolerance, or ValueTolerance. Implemented as Brent line optimers from NRC.
This implementation sets the LineOptimizing flag to 'true', calls the the superclass's implementation, stores extX as the current step length, and sets the LineOptimizing flag to 'false' again.

Get the value of the n-dimensional cost function at this scalar step distance along the current line direction from the current line origin. Line origin and distances are set via SetLine.
This implementation calls the Superclass' implementation and caches the computed derivative's magnitude. Besides, it invokes the SelectNewSamples method.

The LineBracket routine from NRC. Uses current origin and line direction (from SetLine) to find a triple of points (ax, bx, cx) that bracket the extreme "near" the origin. Search first considers the point StepLength distance from ax. IMPORTANT: The value of ax and the value of the function at ax (i.e., fa), must both be provided to this function.
This implementation sets the LineBracketing flag to 'true', calls the superclass' implementation, stores bx as the current step length, invokes an iteration event, and sets the LineBracketing flag to 'false'
