I have compile a doc for AdaBoost.

Thank you very much for reviewing them. I am look forward to your comments.

> Add generic boosting algorithm to spark.ml

>                 Key: SPARK-7129

>             Project: Spark

> The Pipelines API will make it easier to create a generic Boosting algorithm 
> which can work with any Classifier or Regressor. Creating this feature will 
> require researching the possible variants and extensions of boosting which we 
> may want to support now and/or in the future, and planning an API which will 
> be properly extensible.
> In particular, it will be important to think about supporting:
> * multiple loss functions (for AdaBoost, LogitBoost, gradient boosting, etc.)
> * multiclass variants
> * multilabel variants (which will probably be in a separate class and JIRA)
> * For more esoteric variants, we should consider them but not design too much 
> around them: totally corrective boosting, cascaded models
> Note: This may interact some with the existing tree ensemble methods, but it 
> should be largely separate since the tree ensemble APIs and implementations 
> are specialized for trees.
