• added B-spline.
• a base class containing fit and predict so possibly we can reuse docstring across all the interpolation methods.
• [x] trying out docs, will push once done.
• [x] add trend interpolation

Change the spelling of dimention to dimension. Also, make sure comments and docstrings have as minimal grammatical errors as possible.

[sdeepaknarayanan]

Regarding B-Spline, when there are multiple optional arguments, can you mention the argument type as (int, int) or something? kx, ky, as I see it, do not seem to have this. Also add comments mentioning what each variable means. What does "tck" mean for an example? I'll merge once you make the changes

[sdeepaknarayanan]

Is there any reason why function definitions are written your way? The def f(a, B, C) with indentation. I’d avoid that as long as there aren’t too many arguments (<6). No issue tho. We can change later

We should use Black formatter for the code: https://github.com/python/black

[apoorvagnihotri]

Ran black on the following files and directories only:

usage.py
interpolation/trend
interpolation/spline
interpolation/random
interpolation/base

@sdeepaknarayanan I haven't run black on your code files as it will cause problems in merging later.
