Usage:
fixedPoints(M); M stack

Return:
list

Input:
M is a moduli space of stable maps.

Output:
a list of graphs corresponding the fixed point components of a torus action on a moduli space of stable maps.

Example:
 
LIB "schubert.lib";
ring r = 0,x,dp;
variety P = projectiveSpace(4);
stack M = moduliSpace(P,2);
def F = fixedPoints(M);
size(F);
==> 100
typeof(F[1]) == "list";
==> 1
typeof(F[1][1]) == "graph";
==> 1
typeof(F[1][2]) == "int";
==> 1
