CPunch 8ac8085d20 syntax: 'var'->'let' 'function'->'func'
- 'var' has some weird scoping connotations with users of JS. better to change it to 'let', which will decide whether to make the variable a local or a global
- 'func' looks visually appealing lol
- some minor refactoring done in cparse.c

# Cosmo
[![AppVeyor](https://ci.appveyor.com/api/projects/status/github/CPunch/Cosmo?svg=true)](https://ci.appveyor.com/project/CPunch/Cosmo)
Cosmo is a portable scripting language loosely based off of Lua. Cosmo easily allows the user to extend the language through the use of Proto objects, which describe the behavior of Objects. For example the following is a simple Vector Proto which describes behavior for a Vector-like object.
```lua
proto Vector
func __init(self)
self.vector = []
self.x = 0
end
func __index(self, key)
return self.vector[key]
end
func push(self, val)
self.vector[self.x++] = val
end
func pop(self)
return self.vector[--self.x]
end
end
let vector = Vector()
for (let i = 0; i < 4; i++) do
vector:push(i)
end
for (let i = 0; i < 4; i++) do
print(vector:pop() .. " : " .. vector[i])
end
```
```

# C API
The Cosmo C API is currently undocumented, however as soon as development has reached a stable state documentation on full language features and the C API will start.
