Title: Passing CRAN and expanding test coverage

Close #37. Close #38. Accomplish many of the tasks on #32.

Add unit tests for all helper functions for `caretEnsemble`. Expand unit test coverage to smaller helper functions like weighted standard deviations. Fix `summary.caretEnsemble` to produce correct results for ensembled models.

Still need to make the `predict.caretEnsemble` output more consistent across different options.

Fixes a number of issues related to `varImp`, though it does not fail gracefully in the case when `varImp` method fails for a specific method passed to `train`.

Added a new test suite using more diverse `train` methods and some missingness. This checks against some errors relating to building to specifically to the included test models and only increases the size of the package modestly.
