Terms 2.0: son of Terms (#71)

New internal representation of terms of a formula: all are now subtypes of `AbstractTerm`, and any `AbstractTerm` can function as a standalone table-to-matrix converter.

* notes on formula2.0

* is_special guard

* document is_special

* WIP Term types

* operators on AbstractTerms

* overwrite expression with FormulaTerm constructor

* create Terms as last stage of formula macro

* schema for terms

* handle hints

* show methods

* fallback apply_schema for schema dict

* FullRank schema; move schemas to schema.jl

* note on anon functions

* WIP alternative FunctionTerm representation

* more debugging messages

* use (syms...)-> form for FunctionTerms anon functions; fix order

* how to "call" function term

* add getindex and inverse index field to ContrastsMatrix

* fix up/add missing schema methods

* evaluate continuous and categorical terms

* update notes

* don't call terms but use model_cols; exports

* width methods, exports

* rename nt_anon to capture_call_ex!, docstrings

* convenience methods: schema from data.table, apply_schema to formula

* view, don't copy

* termnames

* WIP handle one-sided formula

* WIP replace model frame

* remove dead code from formula.jl

* tweaking schema: use vector instead of set, default to categorical

* add invindex to fulldummy, handle intercepterterm{false}

* add width method for interaction terms

* exports, dispatch/datastreams, bugs in modelmatrix.assign

* WIP adapting tests to new setup

* add termnames and model_cols for formula term; compute catdims

* escape special calls

* add ConstantTerm, convert to InterceptTerm at schema time

* add a few methods to minimic the old Terms fields

* generalized drop_term and term() convenience function

* "safety" fall back for term(::AbstractTerm)

* fixes for apply_schema and ConstantTerm

* delete dead Formula code

* WIP fixing up... (continued)
