Duplicate lectures

As discussed with @jstac , we have some duplicate lectures coexisting in the intro and intermediate lecture series. (cc @mmcky , @HengchengZhang )

Duplicates:

• geom_series: intro, intermediate
• heavy_tails: intro, intermediate (the intermediate one needs to be removed)
• lp_intro: intro, intermediate
• short_path: intro, intermediate

We might consider keeping each of them in only one series.

Also we collect lectures with overlapping contexts here:

1. Markov chain

intro

• https://intro.quantecon.org/markov_chains_I.html
• https://intro.quantecon.org/markov_chains_II.html

intermediate

• https://python.quantecon.org/finite_markov.html

2. Linear algebra

intro

• https://intro.quantecon.org/linear_equations.html
• https://intro.quantecon.org/eigen_I.html

intermediate

• https://python.quantecon.org/linear_algebra.html

3. LLN and CLT

intro

• https://intro.quantecon.org/lln_clt.html

intermediate

• https://python.quantecon.org/lln_clt.html

4. Linear regression

intro

• https://intro.quantecon.org/simple_linear_regression.html

intermediate

• https://python.quantecon.org/ols.html

5. Maximum likelihood estimation intro

• https://intro.quantecon.org/mle.html

intermediate

• https://python.quantecon.org/mle.html

6. Schelling's segregation model

intro

• https://intro.quantecon.org/schelling.html

intermediate

• https://python.quantecon.org/schelling.html

7. Lake model

intro

• https://intro.quantecon.org/lake_model.html

intermediate

• https://python.quantecon.org/lake_model.html

Many thanks @mmcky,

I am removing lectures in the top comment now, and I have requested @jstac's review on the second category.

Thanks @shlff for collecting these and documenting them carefully.

In most cases, the intermediate ones are more advanced and they can co-exist with the intro ones.

However, https://python.quantecon.org/schelling.html is really just a duplicate and can be removed.

Eventually we should connect the related lectures with links between them --- for example, the advanced MLE lecture should refer to the more elementary one at the start and vice versa. But let's put that aside for now.

After removing https://python.quantecon.org/schelling.html and merging @HumphreyYang's PR, I think this issue can be closed.

Many thanks @jstac for your reivew and @shlff for the issue,

I will add schelling into the same PR, remove it from migrated lectures and ping @mmcky for review.
