   3  * @namespace JSDOC
   4  * @class  Packer
   5  * Create a new packer
   6  *
   7  * Use with pack.js
   8  *
   9  *
  10  * Usage:
  11  * <code>
  12  *
  13
  14 var x = new  JSON.Packer(target, debugTarget);
  15
  16 x.files = an array of files
  17 x.srcfiles = array of files (that list other files...) << not supported?
  18 x.target = "output.pathname.js"
  19 x.debugTarget = "output.pathname.debug.js"
  20
  21
  22
  23 x.pack();  // writes files  etc..
  24
  25  *</code>
  26  *
  27  * Notes for improving compacting:
  28  *  if you add a jsdoc comment
  29  * <code>
  30  * /**
  31  *   eval:var:avarname
  32  *   eval:var:bvarname
  33  *   ....
  34  * </code>
  35  * directly before an eval statement, it will compress all the code around the eval,
  36  * and not rename the variables 'avarname'
  37  *
  38  * Dont try running this on a merged uncompressed large file - it's used to be horrifically slow. not sure about now..
  39  * Best to use lot's of small classes, and use it to merge, as it will cache the compaction
  40  *
  41  *
  42  *
  43  * Notes for translation
  44  *  - translation relies on you using double quotes for strings if they need translating
  45  *  - single quoted strings are ignored.
  46  *
  47  * Generation of indexFiles
  48  *   - translateIndex = the indexfile
  49  *
