engine/routines/ stores isolated out-of-context routines as individual files. It might be preferable later to append them to their related engine/ files in unique little SECTIONs, relying on the linkerscript to place them appropriately; or some other organization method. In the meantime, they're now easily findable apart from main.asm's other content.
(This is not expected to be their final location, but it makes them easier to relocate when necessary, and easier for users to edit until the whole project's file structure is finalized.)
Updated macros that rely on the GROUP_, MAP_ constants to use the map macro
Added GROUP_NONE and MAP_NONE for the sake of compatibility with this new scheme
Added new macro elevfloor to simplify the definition of elevators under this new scheme
Replaced encounter rates with percent values
Added new constants denoting the number of wild Pokemon in the grass and water wild constructs
Annotated and relabeled the encounter generating functions
Renamed a WRAM address associaed with the temporary storage of the wild Pokemon's species
Moved spawn constants to constants/map_constants.asm for use anywhere in the disassembly
Trainer data in map scripts is now a macro-defined structure.
Field move functions in main.asm are now nearly completely annotated, with local references.
Trailing white space deleted.
