Deduce and generate data source from user class

```
Allow the user to pass in an instance of any class of theirs and use
introspection to deduce a viable data source for that class, with the idea this
feature would be built into a utility program that generates source code they
can copy and paste into their other program.

Possibly worth allowing them to specify the row class as the main thing to be
introspected with choice of it being stored in a plain array or a custom class
that provides iteration through a series of row instances.
