Detailed Description

template<template< typename, typename > class Callee>
class zethtool::curve_and_snark_resolver< Callee >

Given a class of the form:

template<typename ppT, typename snarkT> class Callee { public: static int execute(std::string &a, ...); };

this class can be used to invoke the correct instantiation of Callee based on curve_name and snark_name strings. E.g.

int r = curve_and_snark_resolver<Callee>("alt-bn128", "groth16", a, ....);
