// Description
// This function calls H5Pcreate to create a new property list
// if the given id, plist_id, is that of a property class. If
// the given id is equal to H5P_ROOT, then set this
// property's id to H5P_DEFAULT, otherwise, to the given id.
// Note: someone else added this code without comments and this
// description was what I came up with from reading the code.
// This function creates a new property list if a property
// class is provided or makes a copy of a property list if one
// is given. If the given id is anything else, then set this
// property's id to H5P_DEFAULT.
