Profile optimize compiler internals fdslke

Describe your changes

Features:

• create a new library type VectorView which provides a lightweight view into a vector
• this new type is to be used primarily with [:] and tail style vector decomposition
• which will immediately allow us to replace List with Vector in Type definition
• there are two branches of the core compiler now index.lsts and dev-index.lsts
• this strategy allows us to develop features inside the compiler without having to "jump" to the next version
