Generate getter functions for public state variables #52
Description
Describe the feature
type public x in contracts should also generate a function x(...) public view returns(...) function that returns the variable. This is more complicated for arrays and mappings.
This should be done during lowering from AST to HIR, by creating a new HIR function.
