PRKernel instances

[Keith Hodges]

Lukas,

I would like to change PRKernel instances to be managed by a KeyedSet. I 
am seeking prior approval before submitting the work.

I am looking forward to a time when there may be many many more pier 
kernels in one system, and the pier application serves them all (or a 
nominated subset) rather than just one.

Lookup performance will be better, especially with the Magma-Pier 
changes that I made to make the application preference a String 
#kernelName rather than a PRKernel instance #kernel.

Also error messages become consistent, e.g. creating a kernel with an 
already existing name.

your thoughts?

Keith
