Reconstruction scripts w/ documentation

[talonchandler]

This PR reinstates a minimal set of example reconstruction scripts that users can modify for "QLIPP" and "PhaseFromBF" reconstructions. These scripts serve as a stopgap between 0.2.0's "Offline Mode" and 1.0.0's plan for a single autogenerated reconstruction mode.

This PR also includes improved documentation for the plugin and the status of automated reconstructions (see the new /docs/reconstruction-guide.md).

I will leave this as a draft, test on hummingbird tomorrow, and request review soon afterwards.

Linking #230.

Since we are making a 100% diff change to ./examples, maybe it's time to remove the now obsolete ./examples/__init__.py? The new scripts are only supposed to be run 'as is' or copy-paste-modified, and does not define any importable object.

This PR may also fix #242.
