SamBuild class
Builder used by SamWatch to build custom Widget tree.
The SamHot variables used by the widgets in the build tree are detected by
placing a marker in SamModel._depBuilders and using WidgetsBinding.instance.addPostFrameCallback
to determine when the build has completed.
Fortunately WidgetsBinding.instance.addPostFrameCallback creates a list of functions to run
when the builder completes so there can be many SamBuild instances in a single widget tree.
This is required because the BuildFunc completes before the widgets are fully rendered.
The BuildFunc is called to allow for the specific widgets to be rendered.
