  53 =head2 UpdateStats
  54
  55   &UpdateStats($params);
  56
  57 Adds an entry to the statistics table in the Koha database, which acts as an activity log.
  58
  59 C<$params> is an hashref whose expected keys are:
  60     branch             : the branch where the transaction occurred
  61     type               : the type of transaction (renew, issue, localuse, return, writeoff, payment
  62     itemnumber         : the itemnumber of the item
  63     borrowernumber     : the borrowernumber of the patron
  64     amount             : the amount of the transaction
  65     other              : sipmode
  66     itemtype           : the type of the item
  67     ccode              : the collection code of the item
  68
  69 type key is mandatory.
  70 For types used in C4::Circulation (renew,issue,localuse,return), the following other keys are mandatory:
  71 branch, borrowernumber, itemnumber, ccode, itemtype
  72 For types used in C4::Accounts (writeoff, payment), the following other keys are mandatory:
  73 branch, borrowernumber, itemnumber, ccode, itemtype
  74 If an optional key is not provided, the value '' is used for this key.
  75
  76 Returns undef if no C<$param> is given
