Created two new files:
- utilities/global/compiler_options.ml: contains
the options that can be set using the cli
- utilities/global/errors.ml: contains global
errors definition
Misc now only contains helper functions that have
nothing to do with the ast or the compiler.
- Global_mapfold is used to iterate over types
defined in Types or Signature (the iterators
from Types were moved here)
- Mls_mapfold to iterate over Minils AST (we
do not iterate over clocks yet: is it useful ?)
