first run at monetary/NK setup

still suffers indeterminacy - rewrite in terms of inflation instead of
absolute price level.
written in terms of Inflation instead price level

still suffers from indeterminacy in B-K conditions, unclear why.
set up compact model doc
NK model doc compact
model doc compact
labor fix

to do: responsive CB interest rate rule
model equations

in flex_price_doc
flex prices st.st. and mod
move NK to separate directory

prepare for merge to dev-branch
NK merge
govt in flex price, responsive int.rate in NK

- delivers determinacy in NK model
- need to figure out how to include "exogenous unanticipated path" for
government expenditures G
started on dispersion measures

analytic derivations in doc
started on adjustment costs

- hard to make work in flex prices
- "works" in NK setting, but no persistence
- made fully "nominal" version in NK model, but need to resolve
indeterminacy of price level
basic version with price adjustment costs
endogenous capital (needs checking)

- results are strange
- documentation is pretty messy
preparing merge

- undo unnecessary changes to GE_NK (for now, maybe replace GE_NK with
GE_NK_adjcost later)
- update gitignore
- added persistence in mod file, and the no-arbitrage eqn in the doc
evaluation and model additions

-added G and M shocks
-a number of functions to evaluate model properties
Finished qualitative evaluation writeup

-Also introduced central bank interest rate smoothing parameter rho_CB
(though it doesn't do too much right now).
preparing merge

(dealing with GE_NK_adjcost.m)
