Fixed: outerProduct was defined incorrectly for unmatched vecX types. E.g. outerProduct(vec2, vec4) did not succeed because the matrix return types were wrong. The computing function seemed fine. I used https://en.wikipedia.org/wiki/Outer_product as reference on what the number of columns/rows ''should'' be and fixed it so that it matches the description from wikipedia

Added: tests for outerProduct with unmatched vector dimensions (actually testing all combinations now)
