calculation CRL with dispersion under Py 2.7

this line brings TypeError: only length-1 arrays can be converted to Python scalars

Could you please provide simple test to reproduce this error?

tutorial3_beamline_focusing_CRL_disp.ipynb, running on Py 2.7
in cell 12

BTW, numpy.exp() in srwlib.py does not help

[buzmakov]

We should pass parameters for srwl_opt_setup_CRL as list

crl_delta = list(be_data[:,1])  # Dummy numbers)
crl_attenuation_length  = list(be_data[:,2]) #Dummy numbers)

May be we should check it in our wrapper create_CRL_....

good point. it was also fix from @CFGrote #80 - is that the same issue?

[samoylv]

@buzmakov fixed?
