Add basic Weles structure
Each interface, used or implemented by many components, should
be defined in the file with the same name as said interface in
basic, weles, package. Definitions of all non-interface types
related to it should be stored in the same file. The remaining
types, if common to multiple interfaces, should be defined
in main package file: weles.go.
The purpose is to have packages to depend on basic package, but not each
other. Moreover a developer will not need to look into documentation or
search for definition of interface as the location of such definition
will be known by interface's name.
This patch also defines manager's interfaces and structures in described
format.
