This class stores a (key,value) pair using an external hash.

The (key,value) are Long64_t's and therefore can contain object pointers or any longs. The map uses an open addressing hashing method (linear probing).

Add an (key,value) pair to the table.

The key should be unique. If the 'slot' is open, use it to store the value, otherwise revert to Add(hash,key,value) This is usually used in conjunction with GetValue with 3 parameters:

if ((idx = (ULong64_t)fMap->GetValue(hash, key, slot)) != 0) {
   ...
} else {
   fMap->AddAt(slot,hash,key,value);
