align functions with camelcase in #12

• There are 3 broken tests, which I don't know how to fix, or identify from the compiler message

• I wanted to suggest functions like mList~> mlist to be manuallist instead since abbreviations are also not recommended

- conciseness is valued, but avoid abbreviation ([indexin](https://docs.julialang.org/en/v1/base/collections/#Base.indexin) rather than indxin) as it becomes difficult to remember whether and how particular words are abbreviated.

The known-broken tests relate to shrinking of BigFloat & BigInt and to preserving invariants when mapping over IntegratedBoundedRec. They should be marked broken in the testsuite. For the former two, it's simply not implemented because generating & shrinking their objects can easily run out of memory, even with the kind of lazy generation we're doing here. For the latter, I haven't found a solution yet. Fixing these is not a priority :)

The whole Manual business is a bit ugly, yes. I wanted to do a bigger refactor at some point of that entire part of the package, but have since recognized that the approach taken in this package is a bit inferior to others. I'm not sure if I'll ever get around to changing that in this package and since this is very much internal, it's fine leaving it as-is.

Other than that, thank you for the PR! I'll leave it open for now and merge it when/if I slate a new breaking release.
