The NCBI standalone blast and web blast plain text output keeps changing 
slightly, and as a result, the parser isn't always up to date.

We recommend you use the XML output instead (this is possible with both 
online blast and the standalone tools).

For the stand alone tools, repeat your searches with the command line 
option -m 7 to get XML output.

If you are using the Bio.NCBIStandalone.blastall() command, use argument 
align_view to set this.

You still use NCBIStandalone.Iterator (if you have multiple queries) but 
now use NCBIXML.BlastParser instead of NCBIStandalone.BlastParser
