 Construct Curve objects from an array of Tenor objects strings as x-axis.
+
+With the `offset` keyword argument the points on the x-axis, defined by the given tenors, can be shifted.
+This could be e.g. used to take a spot lag of financial instruments into account.
+Note that the shift is always in calendar days, a spot lag given in business days must be converted to calendar days beforehand.
