figure out number of observations and tile automatically

[mikofski]

currently

Scalar args need to be tiled or repeated if any of the other argument increase the number of observations, even if that argument is constant.

EG: in the IV curve test the independent variables EE, TC, RS, RSH, ISAT1_0, ISAT2, ISC0, ALPHA_ISC, EG need to be repeated by the size of the diode voltages VD because each diode voltage is another observation.

proposed

review the size of outputs to determine how many observations there are because looking at inputs is not enough

case 1:

input arg increases output size the same - this is the easiest case

case 2:

two input args increase output size in different dimensions, so the output size goes as arg1 * arg2 and it's shape is (arg1, arg2)

case 3:

input arg size is greater than others, but represents collection of constants, coefficients or independent args, EG: values corresponding to different wavelengths which are integrated internally and therefore have no effect on the return
