Editing Findseq (section)

= Usage =
I built this to be rather flexible.  You call it as:
<source lang="python">findseq needle, haystack[, selName[, het[, firstOnly ]]]</source> where the options are:
:: '''needle''' the sequence of amino acids to find.  Should be a string of one letter amino acid abbreviations.  Can also be a string-style regular expression (eg. FW.*QQ).
:: '''haystack''' the PyMOL object or selection in which to search
:: '''selName''' the name of the returned selection.  If you leave this blank, it'll be ''foundSeqXYZ'' where XYZ is some random integer (eg. foundSeq1435); if you supply ''sele'' then the usual PyMOL ''(sele)'' is used; and, finally, if it's anything else, then that will be used verbatim.  Defaults to ''foundSeqXYZ'' so as not to overwrite any selections you might have in ''sele''.
:: '''het''' 0/1 -- if 0 then heteroatoms are not considered; if 1 then they are; defaults to 0
:: '''firstOnly''' 0/1 -- if 0 then all matches are selected and returned; if 1 then only the first is returned
