Detailed Description

The opencl_context_base class represents an OpenCL context in the standard Meyers singleton design pattern.

See the OpenCL specification glossary for a list of terms: https://www.khronos.org/registry/OpenCL/specs/opencl-1.2.pdf. The context includes the set of devices available on the host, command queues, manages kernels.

This is designed so there's only one instance running on the host.

Some design decisions that may need to be addressed later:

we are assuming a single OpenCL platform. We may want to run on multiple platforms simultaneously
we are assuming a single OpenCL device. We may want to run on multiple devices simultaneously
