Some usefull c++ stuff.

Packages

• std : no dependency - a set of containers, strings, stream manipulators, etc. that could almost belong to c++ standard library.

• physics : no dependency - to work with strongly typed arithmetic values representing physic meatures (for instance not to add a length and a duration).

• hash : requires std - hash related features (for instance string_id to obtain a compile-time integer-like object from a string literal).

• type : requires hash & std - to dynamic types utilities (for instance to create them from some register identifier).
