----------------------------
Environment: * (was: * change Params$get to support aliases
support aliases
if the Params contains the specific parameter and alias, but has more than
one value or
if the Params doesn't contains the specific parameter, while the ParamInfo is
optional but has no default value
when isOptional is true, contain(ParamInfo) is true, it will return the value
found in Params, whether the value is null or not. when isOptional is true,
contain(ParamInfo) is false: hasDefaultValue is true, it will return
defaultValue. hasDefaultValue is false, it will throw exception. developer
should use contain to check that Params has ParamInfo or not.
* add size, clear, isEmpty, contains, fromJson in Params
* fix ParamInfo, PipelineStage to adapt new Params
* add test cases about aliases)
> Add more functionalities for ML Params and ParamInfo class
