This new function loads the model from the config file but does not initialize.

3. init() from neuralnet has been updated to loadFromConfig() and does not initialize the model anymore.
Rather call init() after loadFromConfig() to initialize.
This also allows updating the model config after loading model with loadFromConfig().

[tensor] Added axis dimension to average

Current implementation of average() is confusing when compared with sum().
Both sum() and average() do not take axis, and perform similar operations.
However, the semantics of their output is different -
- sum() acts over the dimensions other than batch size
- average() acts over the batch size

To avoid this confusion, average is provided with axis argument with 0 as default.
This is now analogous to sum(axis) than sum()
Further, sum() is renamed to sum_by_batch() as thats what it does and is different from sum(axis)

V2:
Applied the above for lazy_tensor

Minor updates to TensorDim are also made
