 Macros to make parameter definitions a little easier
 Use in a namespace

namespace Metasound
{
	namespace MyNodeVertexNames
	{
		METASOUND_PARAM(InputParam1, "Param 1", "Tooltip for param1.");
		METASOUND_PARAM(InputParam2, "Param 2", "Tooltip for param2.");
		METASOUND_PARAM(OutputParam1, "Out Param1", "Tooltip for output param 2.");
		METASOUND_PARAM(OutputParam2, "Out Param2", "Tooltip for output param 2.");
	}
}

Then to retrieve just do when in a:

using namespace MyNodeVertexNames;

METASOUND_GET_PARAM_NAME(InputParam1)
METASOUND_GET_PARAM_TT(InputParam1)

For variable parameters (e.g. templated on number), do the following:

	namespace TriggerAccumulatorVertexNames
	{
		METASOUND_PARAM(InputParam, "Param {0}", "Do {0} tooltip.");
	}

Then to retrieve the name/tooltip use:

METASOUND_GET_VARIABLE_PARAM_NAME(InputParam, NUMBER);

Where NUMBER is a number (or whatever) to slot into the format specifier you defined in the param def.
