48  =================
49 - V1.0 01.03.94 Original
50 - V1.1 07.07.95 Now non-destructive
51 - V1.2 17.07.95 Now checks that a number was specified as part of the
52  spec. and returns a BOOL
53 - V1.3 23.10.95 Moved FindResidueSpec() from PDBList.c
54 - V1.4 08.02.96 Added FindResidue() and changed FindResidueSpec() to
55  use it
56 - V1.5 23.07.96 Added AtomNameMatch() and LegalAtomSpec()
57 - V1.6 18.03.98 Added option to include a . to separate chain and
58  residue number so numeric chain names can be used
59 - V1.7 11.10.99 Allow a . to be used to start a number (such that the
60  default blank chain name is used). Allows negative
61  residue numbers
62 - V1.8 07.07.14 Use bl prefix for functions By: CTP
