feat: Initial core of picomath Implements a totally simplistic "poortf" mutable typed function and a picomath instance generator, as well as the very beginnings of a number type and one generic function and a default full picomath instance. Also provides some tests which serve as usage examples. 2022-03-25 07:49:03 +00:00			`export default function create(pmath) {`

feat(poortf): add concept of 'author' to an imp of a TF And make it so that if the same author adds imps again, they replace the previous imps from that author. Use this feature to avoid the explicit check for double-inclusion in subtract, and test it worked. 2022-03-25 18:31:06 +00:00			`return pmath(`
