SwarmFit 0.0.3

• SwarmFitter: Improved performance by minimizing allocations (#1) @neon-sunset
• Renamed classes and arguments to favor parameters instead of variables
• SwarmFitter: Use a customizable IRandomNumberGenerator with a default that maximizes performance
• IFunction: Created an interface to help display documented common functions with known typical parameters
• SwarmFit: Refactored to support successive iterative parameter improvements
• QuickFit: Improved default parameters and end optimizing when successive iterations no longer improve the fit
