fix include name NNOps to NnOps

  1. extend different type tensor for sd, memory
  2. inherit super class for polymorphism

Context dev

  1. test idea quickly
  2. sync idea
  3. take type from tensor
  4. make type system in ramtensor

  1. implement add function
  2. implement customized ram tensor constructor

…ensor into featuretensor_refactor

…r into feature_tensor_ref

…ensorConstant

Feature tensor ref initial merge commit

Add python requirements for SD preparation

Featuretensor refactor

…uTensor into featuretensor_refactor

  2. define guard for deep_mnist_mlp for avoid preprocessing non include file
  3. modify main function to focus on refactor point

  2. modify tensorCast for name lookup
