function solve(md,solutionenum){
//SOLVE - apply solution sequence for this model
//
//   Usage:
//      solve(md,solutionenum,varargin)
//      where varargin is a lit of paired arguments of string OR enums
//
//   solution types available comprise:
//               - StressbalanceSolutionEnum
//               - MasstransportSolutionEnum
//               - ThermalSolutionEnum
//               - SteadystateSolutionEnum
//               - TransientSolutionEnum
//               - BalancethicknessSolutionEnum
//               - BedSlopeSolutionEnum
//               - SurfaceSlopeSolutionEnum
//               - HydrologySolutionEnum
//               - FlaimSolutionEnum
//
//  extra options:
//      - loadonly    : does not solve. only load results
//      - runtimename : true or false (default is true), makes name unique
//      - checkconsistency : 'yes' or 'no' (default is 'yes'), ensures checks on consistency of model
//      - restart: 'directory name (relative to the execution directory) where the restart file is located.
//      - callback: callback function to be called upon receiving the results from the server, or local computations. 
//
//   Examples:
//      md=solve(md,StressbalanceSolutionEnum);
