[Biojava-l] how to cancel download chemcomp when parser a PDB file

[Daniel Asarnow]

Prior to this, did setting loadChemComp true add processing overhead if
setAlignSeqRes is also true?  I.e. what's the difference between AlignSeqRes
with and without loadChemComp?
Just want to know what the right flags are when one wants accurate SEQRES
<---> ATOM alignments but isn't otherwise using the components info...

On a related note, I ended up writing a class that loaded and discarded
Structure objects for my PDBs, to trigger all the downloads before my big
processing jobs.  Though I guess the right (non-lazy) thing to do is parse
out the combined components library to the individual files.
