DSL for algorithm variations

[sohale]

DSL for algorithm variations ( interpreter (runtime), or compiler (directly call them) )

(I mean root-finding algorithms, etc)

Almost ready to do, just needs some minor design.

A future direction: Compile-time kernel-fusion for speedup. (or runtime JIT).

( this would make a big difference, will accelerate, will make it much more flexible, and will make development faster )
