   @aaronmarkham made updates according to your comments. Please review the most recent commit. 
   Regarding `FCompute` and `FComputeEx`:
   
   I had a paragraph explaining the why the FCompute interface is limited and cannot be used for sparse ops. Does it make sense? 
   
   > Notice the `FCompute` interface includes TBlobs, which don't include data structures that could be used to query storage
   > types of inputs, nor manipulate auxiliary arrays like `indices` and `indptr`. 
   > Therefore, instead of the `FCompute` interface, sparse operators are registered with the following `FComputeEx` interface
