矩阵乘法

pyschools Topic 6: Question 11题目：矩阵乘法

Write a function that does matrix multiplication.
   The product of a mxn matrix with a nxp matrix results in a mxp matrix.
   A mxn matrix, with m rows and n columns, can be represented using nested lists.
   A_m,n = [ [x₁₁, x₁₂, ..., x_1n], ..., [x_m1, ..., x_mn] ]
