Detailed Description

Base class and default implementation for executives.

Algorithm executives can control pipeline execution by providing a series of requests. this allows for the executive to act as a load balancer. the executive can for example partition requests across spatial data, time steps, or file names. in an MPI parallel setting the executive could coordinate this partitioning amongst the ranks. However, the only requirement of an algorithm executive is that it provide at least one non-empty request.

The default implementation creates a single request for the first index specified by the "index_initializer_key" using the "index_request_key" with "device_id" set to execute on the CPU or GPU (if GPU's are available).
