Remove parsers declaration.

This declaration needed to be removed as it was clobbering the C32 parser when building with grunt.

I left the C32 declaration of ```Parsers``` around, so that holds both C32 & CCDA, otherwise the instance gets blown away with the version included from ccda.js.

Is ```Parsers {}``` required in (standalone) ccda.js for any reason? If so, I probably broke that.

The test suite is broken for me and I'm still coming back up to speed with familiarity of the project and js in general; so there might be a more general/correct way to solve this. (i.e. checking for existence, or moving both declarations to a centralized spot.)If there's a better way to solve this just let me know and I'm glad to fix.
