Parametric Net Pot Remix with Closed Bottom

I just did a remix of leemes "Parametric Net Pot" (https://www.thingiverse.com/thing:790339) and adapted the .scad script so that you can print the bottom of the net-pot without holes when the parameters pie_segments_1, pie_segments_2 and pie_segments_3 are set to 0.

pie_segments_1=0;
pie_segments_2=0;
pie_segments_3=0;
