method chaining options in datatable

[samukweku]

Just a thought on having the functions in datatable also available as methods; primary interest is for visual aspects of it:

DT[:, dt.rowsum(dt.sum(f[:]))]

compared to

DT[:, f[:].rowsum().sum()]

silly example; hopefully it illustrates my thoughts on the visual aspect of it, and how it may help with readable code.

Presently , I abstract code to variables and pass the variables to the frame's brackets:

variable = dt.rowsum(dt.sum(f[:]))

DT[:, variable]

I like this idea, the syntax looks clean. Though it will increase the number of things we need to document.

Great. I'm sure we can incrementally work on documentation
