atomic_weights missing in cython interface

[GoogleCodeExporter]

What steps will reproduce the problem?

1. install cantera 2.1.0
2. create Solution object from python interface, e.g. 

import cantera as ct
gas = ct.Solution('some_mech.cti')

# this works
print(gas.n_species)
print(gas.species_names)
print(gas.molecular_weights)

# the last one doesn't work
print(gas.n_elements)
print(gas.element_names)
print(gas.atomic_weights) # should correspond to former gas.atomicWeights()

3. the last statement fails 

What is the expected output? What do you see instead?

... same as gas.atomicWeights() in old python interface. Elements are 
hard-coded, and not necessarily in species list (see comments on issue 149)

What version of the product are you using? On what operating system?

... svn-r2572 on Fedora 19

Please provide any additional information below.

... my cantera.conf:

prefix = '/opt/cantera-r2572'
python_package = 'new'
python3_package = 'y'
doxygen_docs = True
use_sundials = 'y'
sundials_include = '/usr/include'
sundials_libdir = '/usr/lib64'
blas_lapack_libs = 'lapack,atlas,f77blas,boost_system'
blas_lapack_dir = '/usr/lib64/atlas'
cxx_flags = '-lboost_system'
build_thread_safe = True
