Detailed Description

Provides Leja points (which are nested, i.

e. the set of n leja points is a subset of the set of n+1 leja points). Also accepts a weight function to compute weighted Leja points.

sortedPoints	current Points
points	current Points, new points will be added to this list
number	number of next leja points, new points will be addes to this list
lower_bound	lower bound for the range of the points
upper_bound	upper bound for the range of the points
weight_func	the weight function
