Project Planning:
================
Spider World
- simulation of the effect of spiders as early colonizers of barren and newly emerged territory on the nutrients
- spiders as wind-blown predators that either catch prey and survive, enriching the terrain a lot, or dying, and enritching it just alittle bit.
- in-blown prey (~ eg various diptera)
- prey start to generate in habitat at certain nutrient levels?
- cannibalism important factor
- ~ island biogeography

------
Terrain:
- inherent values:
- 2d dimension
- nutrient values
- varied terrain:
- colonizable land (occupation, nutrient value)
- inhospitable land (can be converted?)
- barriers (water etc. can be crossed by air?)
- (possible terrain _types_)
- Island: uncolonized, nutrient moderate/high
- Emerged land: uncolonize, nutrient poor
Entities ('Critter'):
- inherent values:
- nutrient_value
- position
- lifespan
- (entity type?)
Entity types:
- spiders
- migrate in (ballooning)
- nutrient value
- food necesity
- nutrient recycling
- reproduction
- cannibalism
- species differnces (sedate predators, mobile hunters)
- prey
- migrate in (flying, wind-blown)
- can settle and generate on fertile land?
steps
----
init stuff
loop for n number of ticks:
- immigration() --> check if new entity gets placed, and where
- probability p of a new spider landing in a random location
- prey blowing through terrain (?how and where?)
- actions() --> feed, procreate etc
- check if space occupied by prey
- consume prey
- excrete?
- check for cannibalism? (? species/hunger level dependent?)
- procreate if surplus?
- starve is not fed for long enough?
- live() --> age, check for death, add nutrient to terrain
- update_terrain()
