Find all layers of a type recursively in ArcMap

This code snippit will allow you to return all layers of a type you specify from an mxd.  Very handy code:

public List<ILayer> LoopThroughLayersOfSpecificUID(IMap map, String layerCLSID, bool searchRecursive)
{
/// The different layer GUID's and Interface's are:
/// "{AD88322D-533D-4E36-A5C9-1B109AF7A346}" = IACFeatureLayer
