Clearer Error Message for Duplicate Definition Clearer use of the error message and span labels to communicate duplicaiton defitions/imports. New error format: ``` error[E0428]: the name `Foo` is defined twice --> example.rs:2:1 \| 1 \| trait Foo { } \| ------------- previous definition of the trait `Foo` here 2 \| struct Foo { } \| ^^^^^^^^^^^^^^ `Foo` redefined here = note: `Foo` must be defined only once in the type namespace of this module error: aborting due to previous error ``` 2017-05-17 20:29:58 -07:00			//~^ ERROR the name `X` is defined multiple times

Replace children and import_resolutions with a single NameResolution-valued map. Refactor away resolve_name_in_module in resolve_imports.rs Rewrite and improve the core name resolution procedure in NameResolution::result and Module::resolve_name Refactor the duplicate checking code into NameResolution::try_define 2016-02-07 23:58:14 +00:00			`let _ = foo::X;`
