If the a `DevelopmentConstant()` takes in ldfs, and the triangle applied is smaller (or shorter in length) than the constant, the rest of the constant is discarded. Sample code: ```python...

CaseOutstanding()'s Approach 2 as Proposed by Friedland (2010)

9

The second issue in #159, the `CaseOutstanding()` method can only hand "Approach 1", as demonstrated by [Friedland](https://www.casact.org/sites/default/files/database/studynotes_friedland_estimating.pdf), page 265 (or 271 by count). We are missing Approach 2, as discussed...

Latest n diagonal in heatmap()

8

Is there an easy way to `heatmap()` only the latest n diagonal? I supposed we can add in another parameter, I propose `last_n_diagonal`, default to `None`?

The first issue in #159, there is currently no research literature on how we can estimate residuals for the CaseOutstanding method. As such, the method currently codes the upper triangle...

- Fixed a calculation bug in #497 - Introduced `approximation_grain` in `chainladder.ParallelogramOLF()` - Added two test cases as discussed in #497

For some reason, I can't delete the branch, [#420_to_delete](https://github.com/casact/chainladder-python/tree/%23420_to_delete). @jbogaardt can you look into this to see if it is an admin thing?

#514

- Addressed #514. This is done by removing [secondary_rank](https://github.com/casact/chainladder-python/compare/%23514?expand=1#diff-e4811ac35addcd44905fb8e503aeac1de4816ff160955cd40efe4c3a82c0cc7fL520-L531). @henrydingliu, do you remember why you did this? None of the tests failed, and I couldn't figure out what its supposed...
