Finer control

update so that the functions now coerce the input data to be a dataframe

messages for cart model in the DTModel corrected

allow to choose either the column names or column no.s in the
selectedCols and classCol

In case data is loaded using Rstudio method of import, a tibble instead
of data frame is created. This is not forced to be a data frame (not the
best method).

changed default cross-validation scheme to k-folds

When u used LOSO and a selected number of columns were used, classCol
number becomes different and results in errors.

Major improvements based on Reviewer comments in allowing uniform
cross-validation implementations, confusion matrix additions, addition
of extra functions of overallConfusionMetrics (cross-validation
confusion matrices), predictNewData (prediction of new experiment data).
Addition of relevant references in help.

correction to classperm wrt color

changes to documentation

the plot now refers to dimensions

Pruned trees are not generated for modelNAHF and modelHF

report only 2 significant digits

updated functions to follow a uniform set in the paper

update to be consistent with naming
