[in]	ic	- (IWaveInfo const &) info struct including access to dynamic flags
[in]	k	- (int) spatial order 2k
[in]	ndim	- (int) grid dimension
[in]	gtype	- (IPNT *) grid type array, length = m_size
[in]	stendm	- (int **) stencil dependency matrix, m_size x m_size
[out]	sten	- (STENCIL *) STENCIL struct pointer
