Error when trying to initialize Spin temperature in a 3TM calculation

Hey,

sim.changeInit(3,temp_init) gives an error and it is associated to a typo in line 290 of NTMpy.py version 0.1.1. It says:

self.temp_data_Spin = function

when I believe it should say:

self.temp_data_Spin.init = function

which makes the code run without any issues.

Thanks,

Alberto
