Rewrite salespitch of HDRDA classifier in introduction #15

After the regularization literature review in the introduction, we begin with "Here, we propose the high-dimensional RDA classifier..." I am now of the opinion that this is not the route we want to go. It does not reference to Friedman's (1989) RDA classifier, and at least one reviewer was critical of this.

The wording then needs to change but still maintain a strong presence. Here are working blurbs to add to paragraph or to replace original sentences.

(After brief discussion of Friedman's classifier) We reparameterize Friedman's (1989) RDA classifier so that the resulting covariance-matrix estimator is a convex combination of ... Our parameterization improves the interpretation of the contribution of each observation weighted by the pooling parameter. We show that our parameterization results yields an equivalent, dual decision function that can be efficiently calculated for p >> N.
