1.1.1   Renamed test script to "R-test-10-mtrghost/testPlusMtrGhost.R" and test for ONE (1) function MtrLookupJFun(). Renamed TWO (2) functions MtrFindFunDfr() and MtrFindCmtDfr() to MtrLookupJFun() and MtrLookupJCmt() respectively.
            Fixed TWO (2) errors in function MtrIsComment(): (a) typo "cmtDfr" changed to "cDfr"; (b) parameter "tokenStr" changed to "first" - if numeric, then "first" refers to the position within a line, else it is a "token" character.
