+Adding support for indexes (ie accessing historical values in the model) there are some edge cases around branches that need to be worked through.

 BREAKING CHANGE. Adding support for altering the initial values of new instances of stocks and flows ended up requiring a lot of fundalmental changes, the big one being separating the initialization of model structs for the logic of a loop. Previously these both lived in the run block (`for 2 run{...}`) but now the run block has a optional `init{}` clause where initializations go, leaving the run block with just the steps the happen in the loop. The documentation and example specs have been updated to reflect this new construction.
