	AbstractTimestepper (const JSONValue &json, AbstractAssembler< VectorType, SparseMatrixType, dim > *assembler, DataOutput< dim, VectorType > *data_out=nullptr, AbstractAdaptor< VectorType > *adaptor=nullptr)
	Construct a new Abstract Timestepper object.
DataOutput< dim, VectorType > *	get_data_out ()
	Utility function to obtain a DataOutput object. If no DataOutput object is provided, a default one is created.
AbstractAdaptor< VectorType > *	get_adaptor ()
	Utility function to obtain an Adaptor object. If no Adaptor object is provided, a default one is created, which is the NoAdaptivity object, i.e. no mesh adaptivity is used.

Any derived class must implement this method to run the timestepping algorithm.

Parameters

initial_condition	A pointer to a flowing variables object that contains the initial condition.
t_start	The start time of the simulation.
t_stop	The run method will evolve the system from t_start to t_stop.
