ConstantOverTime overlapping

[lukecampbell]

If I set a parameter value using ConstantOverTime, and set it again later, the latest one completely overwrites the first.

data_dict = {'sparseness' : ConstantOverTime('sparseness', 4096, time_start=0, time_end=3000)}
cov.set_parameter_values(data_dict)
data_dict = {'sparseness' : ConstantOverTime('sparseness', 2048, time_start=30, time_end=3000)}
cov.set_parameter_values(data_dict)

Results in

><> cov.get_parameter_values(['sparseness']).get_data()
-->

       (2048.0, 37.0), (2048.0, 38.0), (2048.0, 39.0)],
      dtype=[('sparseness', '<f8'), ('time', '<f8')])
