Create tutorial on how to use SMILE's machine learning text classification

[longshuicy]

SMILE has support for ML based text classification.
But it's might not be intuitive to use

• can use some touch-up
• come up with step-by-step tutorial

Ability to take two groups of the data – e.g.a sample of 1,000 videos labeled as “pranks” and 1,000 videos labeled as “non-pranks” and use it to build a classifier to recognize pranks. The classifier could be trained on any combinations of the textual and/or visual data (e.g., titles and thumbnails). Have sample code for this.
