Cleaned up Ones and ones

Wrote program to generate those broadcasted ops
Renamed BroadcastMul to BroadcastHadamardProd. BroadcastMul is coming soon

…to create dense triangular matrices

…supported!

…e interfaces more consistent. Previously inversef32 gave the wrong ʘUnaryOperatorType

…now the last axis. This allows for SoftMax to be done across ndarrays

Added more examples

This allows for easier lifting of the return value, however its
utility is not known at the moment.

    Refactor the max/sum ops to share common code. Have the type/inferShape/Do methods behave in a consistent manner: (#346)

    * Dimensions specified in the "along" parameter are reduced to size 1, but not removed. (Note: this caused TestRepeatOpDoDiff, but this version fixes it.  Perhaps we should make preserving the size-1 dimensions an option of the reduction op?)
    * If all dimensions are included, the result will be a scalar.
    * If all dimensions but 1 are included, the result is a vector, regardless of which dimension is left intact.

    Tests verify that the resulting nodes have the expected shape.

    Note: While here, fix a warning on Max's SymDiff where retVal[0] is set when retVal has not been initialized.  I wonder if this is related to #323 where SymDiff for StableSoftMax (which uses Max) was failing with a panic (probably not, as the error message there seems unrelated, but probably a good fix anyway).

    Closes #326
