projectile_least_squares

projectile_least_squares:
  Use a least squares solver to seek minimizer 
  of sum-of-squares error for projectile data.

  c = (   1097.714285714286,   4.571428571428354,   -17.1428571428571)
  f(c) =    45.71428571428572
  f'(c) = (3.24718e-12,5.35039e-12,3.20739e-11)

  Compare values from Professor Layton's notes:

  c2 = (         1097.714286,         4.573428573,        -17.14285714)
  f(c2) =    45.71440572704612
  f'(c2) = (0.0400031,0.120006,0.800039)
