find some some points

find some some points. Note: input is towerClusterVec and stripClusterVec results are stored in mHit, and the return Int_t is an error code or kStOK. Note: this algorithm does not use the tower clusters at all, but just checks the energy of individual towers.

Implements StEEmcPointFinder_t.

"to form a valid smd point, we require a struck tower, or a "fail" bit to be set and one of the other tower detectors to fire (pre/postshower)."

"furthermore, we may require a degree of energy matching between the smd hits"

"create associative arrays matching smd clusters to hits, or in this case index into the smdhits array. NOTE– from here on, it is important that smdhits do not get sorted."
