Is there a function for line-line intersection?

[davibarreira]

Hey, thanks a lot for the package. I was wondering if there is a function for line-line intersection, or perhaps line-segment to line-segment intersection. I've tried the meet function, but it does not work. I've also tried the get_line_intersection, but it returns an error.

Here is a simple example:

a = up(0)
b = up(cl.e1 + cl.e2)
l1 = (a ^ b ^ cl.einf).normal()

a = up(2*cl.e2)
b = up(2*cl.e1 + 2*cl.e2)
l2 = (a ^ b ^ cl.einf).normal()

meet(l1,l2) # returns 0
get_line_intersection(l1,l2) # error
