Since now we have supported Pearson Correlation, which has 2 input columns, and we also have the use case call from #424, we are calling that we should have AggIntent to support a vector of columns as input, instead of a single one.
The input_col() trait method should be modified to input_cols(), which returns a vector, so on and so forth. Current one-input AggIntent can fall back to a vec with one element.
Will add more details to this issue if you think current one is badly described. Please leave comments for that.
