// Function: make_path_valid()
// Function: check_and_fix_path()
// Usage:
// make_path_valid(path, [valid_dim], [closed])
// Description:
// Checks that the input is a path. If it is a region with one component, converts it to a path.
// valid_dim specfies the allowed dimension of the points in the path.
// If the path is closed, removed duplicate endpoint if present.
// Arguments:
// path = path to process
// valid_dim = list of allowed dimensions for the points in the path, e.g. [2,3] to require 2 or 3 dimensional input. If left undefined do not perform this check. Default: undef
// closed = set to true if the path is closed, which enables a check for endpoint duplication
