读、写和操纵PTX

Implements object model and infrastructure for reading, writing and manipulating codes of PTX assembly language. The object model provided is a strongly-typed replica of the ISA, i.e. its potential uses are two-fold: firstly, as an error-free way to parse and emit PTX and, secondly, as a source of programmatic introspection into the ISA. Currently, the library is built against PTX ISA 2.1 (but supports previous versions as well). More information can be found in the readme.
