Added minval, maxval, and seed arguments to the RandomUniformInitializer
Added unit tests for Gather and a simple Embedding test.

Added 2D global max pooling and unit tests.
Disabled one max pooling test, needs further investigation,

Currently the `TensorFlowOpLayer` test will fail on the function `fit` so I put the Attribute `Ignore`  on it.
