Abstract template base class for computing for a linear operator C and a vector s. submit_jobs method creates a bunch of jobs needed to solve for this particular and attaches one unique job aggregator to each of them, then submits them all to the computation engine.

Abstract template base class that represents a linear operator, e.g. a matrix.
Abstract base class for solving multiple independent instances of CIndependentJob. It has one method, submit_job, which may add the job to an internal queue and might block if there is yet not space in the queue. After jobs are submitted, it might not yet be ready. wait_for_all waits until all jobs are completed, which must be called to guarantee that all jobs are finished.
