v0.3.0

Changes

• Flesh out HTML::MyHTML parser class
• FIrst go at HTML::MyHTML::Tree that is mostly just wrapping for raw routines but also builds H::M::Collections
• First pass HTML::MyHTML::Collection class that provides easy access to nodes via positional subscripts
• First pass HTML::MyHTML::Node class that has many helper methods to traverse nodes and print them
• Some work on manipulating the text in the tree (though a MyHTML C renderer is NYI)
• Many raw reprs were changed to CPointer as the internal structures were not needed
• Some bugs in Raw interface squashed (Raw.pm6 should still be considered beta but most of it should work)
