docs: PARTIAL // 
  FUNCTION: partial( lambda, k )
  Partially applies shape parameter `lambda` and scale parameter `k` and returns a function for evaluating the quantile function for a Weibull distribution.
  
  @param {Number} lambda - shape parameter
  @param {Number} k - scale parameter
  @returns {Function} quantile function
