started SVM routine. Need to investigate performance of ensemble over partition training set versus single over whole training set.
updated svm.R and built speed-test script to determine speed vs. accuracy of linear vs. gaussian kernels.

updated svm_speed-tests to increase sample size and take into account new load_data.R
up'd sample.sizes, modified training.set size, and fixed workspace.vars issue when saving speed-test results.
wrote cross-validate routine to determine optimal cost on full data.
fixed conflicts
