Fixing a few hundred clear typos with the help of Claude. Some are less important in code comments, but majority of them are in user-facing places. I manually approved 60%+ of the changes and didn't see any that were an incorrect suggestion, at worst it was potentially uncessesary, like a code comment having cant instead of can't. No RM.

 /* metaRa - stuff to parse and interpret a genome-hub meta.txt file, which is in 
  * a hierarchical ra format.  That is something like:
  *     meta topLevel
  *     cellLine HELA
  *
  *         meta midLevel
  *         target H3K4Me3
  *         antibody abCamAntiH3k4me3
  *       
  *            meta lowLevel
  *            fileName hg19/chipSeq/helaH3k4me3.narrowPeak.bigBed
  * The file is interpreted so that lower level stanzas inherit tags from higher level ones.
  * NOTE: this file has largely been superceded by the tagStorm module, which does not
  * require meta tags, but is otherwise similar.
