In glmnetr: Nested Cross Validation for the Relaxed Lasso and Other Machine Learning Models

################################################################################  
#' Summarize a nested.glmnetr() output objects version 0.5-1
#'
#' @description 
#' Summarize the model fit from a nested.glmnetr() output object, i.e. the fit of 
#' a cross-validation informed relaxed lasso model fit, inferred by nested cross 
#' validation.  Else summarize the cross-validated model fit.    
#'
#' @param object a nested.glmnetr() output object.  
#' @param cvfit  default of FALSE to summarize fit of a cross validation informed 
#' relaxed lasso model fit, inferred by nested cross validation.  Option of TRUE 
#' will describe the cross validation informed relaxed lasso model itself. 
#' @param pow the power to which the average of correlations is to be raised.  Only 
#' applies to the "gaussian" model.  Default is 2 to yield R-square but can be on to 
#' show correlations.  Pow is ignored for the family of "cox" and "binomial".   
#' @param printg1 TRUE to also print out the fully penalized lasso beta, else to suppress.  
#' Only applies to cvfit=TRUE.
#' @param digits digits for printing of deviances, linear calibration coefficients 
#' and agreement (concordances and R-squares).
#' @param Call 1 to print call used in generation of the object, 0 or NULL to not print 
#' @param onese 0 (default) to not include summary for 1se lasso fits in tables, 1 to include 
#' @param table 1 to print table to console, 0 to output the tabled information to a data frame
#' @param tuning 1 to print tuning parameters, 0 (default) to not print
#' @param width character width of the text body preceding the performance 
#' measures which can be adjusted between 60 and 120.
#' @param ... Additional arguments passed to the summary function.  
#' 
#' @return - a nested cross validation fit summary, or a cross validation model summary.
