NAME : FormChain
DESCRIPTION : Builds a list of classes to be used in
instance queries - uses parse form.
INPUTS : 1) Name of calling function for error msgs
2) Data object - must be a symbol or a
multifield value containing all symbols
The symbols must be names of existing classes
RETURNS : The query chain, or NULL on errors
SIDE EFFECTS : Memory allocated for chain
Busy count incremented for all classes
NOTES : None
