engforge.properties

Like typical python properties, normal functions are embelished with additional functionality.

system_properties is a core function that adds meta information to a normal python property to include its output in the results. It is the “y” in y=f(x).

class_cache a subclassing safe property that stores the result at runtime

solver_cache a property that is recalculated any time there is an update to any attrs variable.
