> Scala ML examples code merge and clean up

>                 Key: SPARK-14299
>                 URL: https://issues.apache.org/jira/browse/SPARK-14299
>             Project: Spark
>          Issue Type: Sub-task
>          Components: Examples

> Duplicated code that I found in scala/examples/ml:
> * scala/ml
> ** CrossValidatorExample.scala --> ModelSelectionViaCrossValidationExample
> ** DecisionTreeExample.scala --> DecisionTreeRegressionExample, DecisionTreeClassificationExample
> ** GBTExample.scala --> GradientBoostedTreeClassifierExample, GradientBoostedTreeRegressorExample
> ** LinearRegressionExample.scala --> LinearRegressionWithElasticNetExample
> ** LogisticRegressionExample.scala --> LogisticRegressionWithElasticNetExample, LogisticRegressionSummaryExample
> ** RandomForestExample.scala --> RandomForestRegressorExample, RandomForestClassifierExample
> ** TrainValidationSplitExample.scala --> ModelSelectionViaTrainValidationSplitExample
> ** DeveloperApiExample.scala --> I delete it for now because it's only about how to
create your own classifieri, etc, which can be learned easily from other examples and ml codes.
> ** SimpleParamsExample.scala --> merge with LogisticRegressionSummaryExample.scala
> ** SimpleTextClassificationPipeline.scala --> ModelSelectionViaCrossValidationExample
> ** DataFrameExample.scala --> merge with LogisticRegressionSummaryExample.scala
> When merging and cleaning those code, be sure not disturb the previous example on and
off blocks.
> I'll take this one as an example.
