Xu Yang updated FLINK-13668:
----------------------------
    Description: 
_FlatMapper transforms one Row type data into zero_, _one_, _or more Row type 
result data_, _and Mapper transforms one Row type data into one Row type result 
data. For most of practical_ *scenarios*, *the outputs are single column. Using 
these extend classes*, *we can be more focus on the algorithm development.*
 * *Add SISOFlatMapper for the Single Input column and Single Output column 
scenario.*
 * *Add SISOMapper for the Single Input column and Single Output column 
scenario.*
 * *Add MISOMapper for the Multi Input column and Single Output column 
scenario.*
 * *Add Param definition for SISOFlatMapper*
 * *Add Param definition for SISOMapper*
 * *Add Param definition for MISOMapper*
