Add QSpinBox widgets for entering degree and height #5
Description
Currently, the app will generate all polynomials, root sets, and circles before even launching the app. Instead, the app should open with a blank OpenGL widget, a button that generates and draws the circles, and QSpinBox widgets to configure the maximum degree and height of polynomials generated.
