Piyush Katyal a24450a629 feat: add determinant algorithm (#1438)
* feat: add determinant calculating algorithm

* test: add self-tests for determinant algorithm

* chore: add wikipedia info link

* fix: change initialization to zero

* fix: add error throw and general code improvements

* fix: add error try and catch

* fix: seperate the test loops of error cases

* clean up a bit
