FENICS Exports, solves, and imports a FEniCS project.

[ PROB ] = FENICS( PROB, VARARGIN ) Export, solves, or imports the solved problem described in the PROB finite element struct using the FEniCS project solver. Accepts the following property/value pairs.

Input       Value/{Default}              Description
modes       data, export, solve, import  Command mode(s) to call (default all)
