Create a tbl_graph object with cycles information

Create a tbl_graph object with cycles information

sfcr_dag_cycles(equations)

Arguments

equations	A `sfcr_set` containing all the equations of the model to be simulated. The equations must be written with the R formula syntax, with the left-hand side separated from the right-hand side by a twiddle `~`.

A tbl_graph

This function creates a tbl_graph with information about the cycles attached to it. This object can then be used to plot the DAG of the model.
