File dependencies within tasks

A task should be able to depend on a file being generated, like Rake.

Something like:

aTask:Produces('myFile.lua') -- Produces a file

anotherTask:Requires('myFile.lua`) -- Calls aTask first

Using patterns and wildcards would be nice

-- Anything that looks like {name}.lua is replaced with {name}.min.lua. 
-- What we actually do is when {name}.min.lua is requested we pass in {name}.lua {name}.min.lua
-- This isn't as intuitive, but from a code position, makes more sense
aTask:Maps('ptrn:%1%.lua', 'ptrn:.+%.min%.lua') 

-- Wildcards are just replaced at runtime. '*' is replaced with '(.*)' or '%1'.
aTask:Maps('wild:src/*.lua', 'wild:build/*.lua')

-- Runs aTask with `something.lua` as an argument.
anotherTask:Requires('something.min.lua')
