Steps

• Implement graph
  • Take all operations and link them all based off input and output data types
  • Linker dffml/df/linker.py will probably be helpful
• Take input of what output data is desired
• Take input of what input data is available
• Output a dict describing needed input

Example

The output of Linker.export()["operations"] is:

{
  "op1": {
    "inputs": {
      "in1": "in1_type"
    },
    "outputs": {
      "out1": "out1_type"
    }
  },
  "op2": {
    "inputs": {
      "in2": "out1_type"
    },
    "outputs": {
      "out2": "out2_type"
    },
  "op3": {
    "inputs": {
      "in3": "out2_type"
    },
    "outputs": {
      "out3": "out3_type"
    }
  } 
}

User says to dependency backtrack, I want out3_type and have in1_type

Output of dependency backtrack: TDB
