Subproblem objectives

This objective can be use when the objective of a sub problem solver still needs access to the (outer/main) objective.

Manopt.AbstractManifoldSubObjective — Type

AbstractManifoldSubObjective{O<:AbstractManifoldObjective} <: AbstractManifoldObjective

An abstract type for objectives of sub problems within a solver but still store the original objective internally to generate generic objectives for sub solvers.
