The library seems to work and is stable so this is the 1.0 release. Thanks to @sbrugman, we now display tensor element type information using both color and text. The color indicates the type (int, float, complex, ...) and the transparency level indicates the precision; the more saturated the color, the higher the precision. Github doesn't seem to render notebooks with pictures very well anymore so take a look at the colab version.
