> ML {{GeneralizedLinearRegression}} only support lowercase input for {{family}} and {{link}}
currently. For example, the following code will throw exception:
> {code}
> val trainer = new GeneralizedLinearRegression().setFamily("Gamma")
> {code}
> However, R glm only accepts families: {{gaussian, binomial, poisson, Gamma}}. We should
make {{family}} and {{link}} case insensitive.
