 This problem involves the `OJ` data set which is part of the `ISLR` package.	
 * Create a training set containing a random sample of 800 observations, and a test set containing the remaining observations.	
 * Fit a support vector classifier to the training data using `cost=0.01`, with `Purchase` as the response and the other variables as predictors. Use the `summary()` function to produce summary statistics, and describe the results obtained.

 Here we explore the maximal margin classifier on a toy data set.
 * We are given n = 7 observations in p = 2 dimensions. For each observation, there is an associated class label.
