defining possible data types within categorical variables

[CamilaAchuri]

when the only result within a categorical variable is greater than 30 it should not be defined as Cat, assess when it makes sense for it to be categorised as text or think about how it is defined.
Think also about the cases when they are ordered categories and the condition when it comes to pie charts where no more than 6-7 categories should go

Leaving some notes here:

• Issue of hdtype while guessing Cat Guess Cat with many categories as Txt hdtable#7
• Ord as subtype of Cat Add Ord as a subtype of Cat hdtable#8
• Put in dsprep the cases for aggregation of "Others" when there are many small categories
