Feature Request - Vector and Matrix User Input Field

[imartincei]

Currently, the HTML UI elements can only return a single value. It would be very nice to have fixed or dynamic sized vectors/matrixes (basically a list/table of input variables) as part of the input options, so people don't have to edit the source code to input these variables.

An example use case is a for loop that runs the same design case for different conditions. For example, checking multiple spans of the same steel beam with the number of spans being completely dynamic.

Something with behavior like this would be ideal:
