New git directory for Numerical Analysis homework and project code.
Added chebyshev.C, which produces a list of the coefficients for a number of
Chebyshev interpolating polynomials, determined at runtime, for a function
specificied within the code (currently f(x) = cos(pi*x) or something simiilar).
