ssa()

def ssa.ssa	(		n,
			h,
			K,
			f,
			T
	)

ssa -- multi-stage (serial) safety stock allocation model
Parameters:
    - n: number of stages
    - h[i]: inventory cost on stage i
    - K: number of linear segments
    - f: (non-linear) cost function
    - T[i]: production lead time on stage i
Returns the model with the piecewise linear relation on added variables x, f, and z.
