[docs] Documentation headings unclear

[nikochiko]

Scenario:

• Documentation headings are confusing:
  • Basics of Using the Exported Keras Model and Use exported model in Keras
  • Using an Exported Caffe Model and Use exported model in Caffe
• Also, in Using an Exported Caffe Model, the numbering of the text after the example looks to be wrong. (Execute the following using ...)

Expected:

• Names can be more clear. Like the "Basics of Using the Exported Keras Model" can be renamed as "Loading an exported Keras model" and similarly for Caffe.
• Numbering can be fixed.
