    JIRA: MADLIB-915
    
    Authors:
    Xiaocheng Tang <xiaocheng.t@gmail.com>
    Rahul Iyer <rahiyer@gmail.com>
    
    Changes:
    - Add cross validation support on lambda, epsilon, init_stepsize, max_iter, and decay_factor
    - Add support for optionally writing validation results to a sql table
    - Add support for lazy-generation of cv datasets
    - Add internal generic CrossValidator class which is used for implementing this issue
    - Refactoring SVM for better modularity
    - Ignore cv on epsilon when it is classification
    - Cross validation now works when independent variables are queries
    - Fixed "zero length field name in format" error in python < 2.7
    - Fix error messages so that it pass the svm input tests
