Implement [DataFrame Series].fillna() and [DataFrame, Series].dropna()

[sethmlarson]

fillna() can be implemented as a post-processing task. dropna() can be implemented as a query filter

For now we can support axis only as axis=1 for "columns", some options may be supportable but others may be tougher.

I'll try to implement this

• Similar to Pandas

• For dropna -> axis=columns and how=all

• Fillna as postprocessing task can be done.

So, I need to think of how to do Axis=rows and how = any

Any inputs ? 🙂
