Tdiff::Core

The core module is in charge of comparing already parsed Tdiff::Tree objects and returning an array of Tdiff::Core::Result.

The way it works, in general, is the following:

A Tdiff::Core::Comparator receives two trees. Navigates them recursively, and whenever it encounters a scalar value on either side, it uses a Tdiff::Core::Comparison, and if there's a difference it is stored for later use.

Note that the reason of the determined difference is also stored on the Tdiff::Core::Result object, by way of the enumeration Tdiff::Core::DifferenceReason

There's still no way to add custom or different algorithms for the tree comparison (which for example, could benefit of a non-recursive approach or even a parallel one for VERY large files).
