Creating Foot Controls

REMINDER: Hold d and v to move the pivot

Add a nurbs (circle) > control vertex then shape the nurb so it looks like a foot

then click on edit in channel menu > add attribute. Make sure the attribute is keyable and the data type is float. Name it the Heel Lift. Repeat this for the Toe lift, Pirouette UD, Pirouette LR and Foot roll.

There's a lot of attributes we don't need so to help navigate the attributes, you can hide the ones we aren't going to use by
