Polynomial Wizard

[jonmoore]

I think this is an excellent new edition to the Prime. In many ways, it reminds me of the wizards on Casio calculators, and that's no bad thing.

I do have a couple of suggestions for improving the UX:

1.) It would be really useful if one of the softkeys enabled the user to copy the polynomial for use in the graphing apps (after apt transformation, if required).

2.) It would be better if the matrix brackets were implicit (self populated) that way the user would only need to enter the coefficient/root values separated by commas. The UX would be less prone to student error and cleaner.

BTW coefficient is currently spelt incorrectly.
