  Step 1: reduce use of large arrays.

  Getting rid of large arrays: axisx & data

  mapDiffaToRaphael:
  array with 2-minute intervals' timestamps
  this is used to bucket fdData into clusteres, which go into 'clusters' array
  DONE

  setupHeatmapConfig:
  sticks axisx in config
  axisx.length used to get total number of increments
  DONE

  drawXAxis:
  'now' is created from the last entry in axisx (and then not used!) axisx is iterated through to map to an array that contains those values that round to the nearest hour
  DONE

  drawBlobs:
  axisx.length is used as the upper limit on a loop
  the loop only looks at data points; each data point's timestamp is needed, which is pulled from axisx
  DONE

  scrollHeatmapTo:
  axisx.length is used
  DONE

  ----- what we'd need to save -----

  axisx.length
  now (=axisx[axisx.length-1])
  the value of axisx for each data point

  (from [847e997b13a085462b2023fbe05384515ffedba1]) Removed use of large arrays axisx & data. This has had a reasonably positive effect on the performance. There is still some work to do to remove the circular reference between each blob (a SVG element) and its cluster (a JS object). I am going to open another ticket for that and set it to v1.0.

  There has also been some miscellaneous tidying up, mainly to make sure that variables are not duplicated or inconsistently named.
