Pre-Release 2.10.1

1. In the `gene_space` parameter, any `None` value (regardless of its index or axis), is replaced by a randomly generated number based on the 3 parameters `init_range_low`, `init_range_high`, and `gene_type`. So, the `None` value in `[..., None, ...]` or `[..., [..., None, ...], ...]` are replaced with random values. This gives more freedom in building the space of values for the genes.
2. All the numbers passed to the `gene_space` parameter are casted to the type specified in the `gene_type` parameter.
