=head1 NAME
C4::Stats - Update Koha statistics (log)
=head1 SYNOPSIS
use C4::Stats;
=head1 DESCRIPTION
The functions of this module deals with statistics table of Koha database.
=head1 FUNCTIONS
=head2 UpdateStats
&UpdateStats($params);
Adds an entry to the statistics table in the Koha database, which acts as an activity log.
C<$params> is an hashref whose expected keys are:
branch : the branch where the transaction occurred
type : the type of transaction (renew, issue, localuse, return, writeoff, payment
itemnumber : the itemnumber of the item
borrowernumber : the borrowernumber of the patron
amount : the amount of the transaction
other : sipmode
itemtype : the type of the item
accountno : the count
ccode : the collection code of the item
type key is mandatory.
For types used in C4::Circulation (renew,issue,localuse,return), the following other keys are mandatory:
branch, borrowernumber, itemnumber, ccode, itemtype
For types used in C4::Accounts (writeoff, payment), the following other keys are mandatory:
branch, borrowernumber, itemnumber, ccode, itemtype
If an optional key is not provided, the value '' is used for this key.
Returns undef if no C<$param> is given

Returns an array containing the payments and writeoffs made between two dates

If C<$time2> eq '', results are returned from C<$time> onwards.
If C<$time2> is undef, returns are limited to C<$time>
C<$spreadsheet> param is optional and controls the sorting of the results.
Returns undef if no param is given
