dim(Fan) -- computes the dimension of a fan

Synopsis

Function: dim
Usage:

d = dim F
Inputs:
- F, an instance of the type Fan
Outputs:
- d, an integer

Description

Returns the dimension of a fan. This is the maximal dimension of all cones of the fan.

i1 : F = hirzebruch 3

o1 = {ambient dimension => 2         }
      number of generating cones => 4
      number of rays => 4
      top dimension of the cones => 2

o1 : Fan

i2 : dim F

o2 = 2
