neuralIdeal -- computes the neural ideal of a neural code.

Usage:

neuralIdeal(C)
Inputs:
- C, a NeuralCode
Outputs:
- an ideal, the neural ideal of C in ring C

Description

This method computes the neural ideal using the method of Curto, Itskov, et al. The returned ideal is not in general in canonical form.

i1 : C=neuralCode({"000","001"});

i2 : ring C;

i3 : I=neuralIdeal(C)

o3 = ideal (x x x  + x x  + x x  + x , x x x  + x x , x x x  + x x  + x x  +

              ZZ
o3 : Ideal of --[x ..x ]
               2  1   3

i4 : ring I
