Calculates the zeros of the first derivatives of Bessel function.
Updates BessDerivZerosBisect.m with these changes:
1. Allows for m = 0
2. Allow the user to specify the particular m and k values desired.
3. Allows for a tolerance input parameter
4. Uses a table look-up to get closer initializations for small values of m and k.
5. Adds error checking
6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.)
