Using the built-in Math.pow method instead of svm's custom powi. This makes the code faster.

Using the built-in
Math.powmethod instead of svm's custompowi. This makes the code faster.I checked this by sampling svm prediction with
jvisualvm.powiused to take about 8-10% of the CPU time (withKernel.dottaking 66-73%). After changing it toMath.powthe time it takes is negligible.
