VectorAssembler is a transformer that combines a given list of columns(vector or numerical column) into a single vector column. VectorAssembler accepts the following input column types: all numeric types, and vector type. In each row, the values of the input columns will be concatenated into a vector in the specified order.
 * Add VectorAssemblerMapper for the operation of the vector assemble.
 * Add VectorAssemblerParams for the parameters of VectorAssemblerMapper.
 * Add VectorAssemblerMapperTest for the test example.
