Provides a place for environmental variables. Currently lets you set boundaries on the base, the op_code_width and the operand_width. Used for validation during initialization.
Doesn't take any arguments and returns a hash ref with three keys - base, op_code_width and operand_width. Each in turn is a reference to a hash which has a key called min and another called max.
Used by VM::Dreamer::Validate to validate the machine definition during initialization and by VM::Dreamer::Error to populate an error string with the min/max values for a more robust error message to the user.
Returns a analog of base, op_code_width and operand_width suitable for use in strings when presented to a human. Used by vM::Dreamer::Error.
