Release v2.1.0 Seki · Zushah/Chalkboard

The eleventh release of the Chalkboard library, version 2.1.0. Main updates include:

Changed all of the matr commands to work significantly faster for 2x2, 3x3, and 4x4 matrices (for example, multiplications are about 67% faster, inversions are about 85% faster, and determinants are about 95% faster) when compared with previous versions of Chalkboard
Added a total of 26 .isFoo commands in the matr, tens, and vect categories that check if a matrix, tensor, or vector fulfills a particular property (for example, matr.isDiagonal checks if a matrix is a diagonal matrix)
There are also 14 more matrix commands, such as matr.diagonal, matr.eigenvalue, matr.eigenvector, matr.norm, and matr.perm
Changed the parameters of matr.adjugate, matr.concat, matr.cofactor, matr.push, matr.pull, matr.toVector, and vect.toMatrix in a few different ways (details are in the detailed changelog below)
Removed matr.binomial and matr.shift and replaced them with matr.lowerBinomial, matr.symmetricBinomial, matr.upperBinomial, matr.lowerShift, and matr.upperShift
