function solve(md,solutionstring){
//SOLVE - apply solution sequence for this model
//
//   Usage:
//      solve(md,solutionstring,varargin)
//      where varargin is a lit of paired arguments of string OR enums
//
//   solution types available comprise:
//               - 'Stressbalance'      or 'sb'
//               - 'Masstransport'      or 'mt'
//               - 'Thermal'            or 'th'
//               - 'Steadystate'        or 'ss'
//               - 'Transient'          or 'tr'
//               - 'Balancethickness'   or 'mc'
//      - 'Balancevelocity'   or 'bv'
//               - 'BedSlope'           or 'bsl'
//               - 'SurfaceSlope'       or 'ssl'
//               - 'Hydrology'          or 'hy'
//      - 'DamageEvolution'   or 'da'
//               - 'Gia'                or 'gia'
//               - 'Sealevelrise'       or 'slr'
//
//  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,'Stressbalance');
//      md=solve(md,'sb');
