Function that forms a wrapper around certain `rags2ridges`

functionalities.
More specifically, it (automatically) invokes functionalities to get from high-dimensional
data to a penalized precision estimate, to the corresponding conditional independence graph
and topology summaries.

The wrapper always uses the alternative ridge precision estimator (see `ridgeP`

) with `target`

as the target matrix. The optimal value for the penalty parameter is determined by employing Brent's method to
the calculation of a cross-validated negative log-likelihood score (see `optPenalty.LOOCVauto`

).
The support of the regularized precision matrix is determined by way of local FDR thresholding
(see `sparsify`

). The corresponding conditional independence graph is visualized using
`Ugraph`

with `type = "fancy"`

. This visualization as well as the calculation
of network statistics (see `GGMnetworkStats`

) is based on the standardization of the regularized
and sparsified precision matrix to a partial correlation matrix.

The function stores in the specified directory `dir`

a condition number plot (either .pdf or .eps file),
a visualization of the network (either .pdf or .eps file), and a file containing network statistics (.txt file).
When `nOutput = TRUE`

the function also returns an object of class `list`

:

`optLambda` |
A |

`optPrec` |
A |

`sparseParCor` |
A |

`networkStats` |
A |

We consider this to be a preliminary version of an envisioned wrapper than will take
better form with subsequent versions of `rags2ridges`

.
