DWARF parser (only the .debug_info section for now) using parslet and unix utilities.

Parses DWARF format, as outputed by the following:

...
λ readelf --debug-dump=info spec/fixtures/c/build/example.so > spec/fixtures/out.dwarves

rake build # Build dwarves-0.1.0.gem into the pkg directory
rake clean # Remove any temporary products
rake clobber # Remove any generated files
rake doc # Generates documentation
rake install # Build and install dwarves-0.1.0.gem into system gems
rake install:local # Build and install dwarves-0.1.0.gem into system gems without network access
rake lint # Runs the linter
rake release[remote] # Create tag v0.1.0 and build and push dwarves-0.1.0.gem to 'https://rubygems.org'
rake test # Run tests
A good test for the parser is to parse its own input, since we reconstruct the output when printing.
