Fix ORTE regex bug:
regex of node1,node3,node002
returned
node[1:1,3],node2
should be
node[1:1,3],node[3:2]
single node case still works:
regex of node002
returns
node002

deleted code is unnecessary because of singlton node case handling at
begining of function
remove debug output
some more tests for orcm regex
add copyright to tests
clarify time reporting in regex large test
