Description

simplcial_polytopic_number.rs is meant to replace triangular_number.rs and tetrahedral_number.rs.

I added simplicial_polytopic_number.rs and rising_factorial.rs to /src/math/.
Simplicial polytopic numbers are a family of sequences of figurate numbers corresponding to the d-dimensionsal simplex for each dimensional simplex for each dimension d, where d is a nonnegative integer.

Rising factorials are defined as the polynomial
(x)_n = x(x + 1)(x + 2)...(x + n - 1)

Type of change

Please delete options that are not relevant.

• New feature (non-breaking change which adds functionality)

Checklist:

• I ran bellow commands using the latest version of rust nightly.
• I ran cargo clippy --all -- -D warnings just before my last commit and fixed any issue that was found.
• I ran cargo fmt just before my last commit.
• I ran cargo test just before my last commit and all tests passed.
• I added my algorithm to the corresponding mod.rs file within its own folder, and in any parent folder(s).
• I added my algorithm to DIRECTORY.md with the correct link.
• I checked COUNTRIBUTING.md and my code follows its guidelines.

Please make sure that if there is a test that takes too long to run ( > 300ms), you #[ignore] that or
try to optimize your code or make the test easier to run. We have this rule because we have hundreds of
tests to run; If each one of them took 300ms, we would have to wait for a long time.
