/**
* Match all newcomer without a referral to a referral
*
* In this algorithme, we first try to match godsons to referral of the same branch
* Then we try to match them we other branch if there is no space left.
*
* Current algorithme as 7 big steps :
*
* * STEP 1 : Creation of $counts and $counts2 arrays.
* $counts is used in steps 2 and 3 to lower the number of queries to DB.
* And $counts2 is used in steps X, X and X to lower the number of queries to DB.
* The only difference between theses two arrays is that user are grouped by branch in the first one.
*
* * STEP 2 : Calculate the future number of godson for each referrals.
* We get the number of newcomers and we add one to each referral until reaching their wanted maximum.
* If there is still newcomers when all maximums are reached, we increment the maximum
* (with $counts[branch]['+1']) for everyone except thoses with a maximum at 5 (6 godsons is really too much)
* and we do it again until reaching the $MAXIMUM_OVERFLOW.
*
* * STEP 3 : Give godsons to referrals according to the calculated value in
* precedent step and according to referral and godsons location.
* For every newcomers, we take all referrals of his branch that have place left
* and we try to match them by full postal_code and country. If there is a match
* We associate them, if there is a multiple match, we take a random referral in the list
* If there is no match we pass this newcomer and try with another one. At the
* end of the newcomer list, we try agains with the newcomer that we have passed
* with another matching solution. We do this again with all theses matching solution :
* * Full postal code
* * French departement code
* * French region
* * Country
* If there is still no match, we try to match newcomers with everyone of his branch
*
* * STEP 4 : Remove PMOM and Master from left newcomers
* We will now try to match newcomers with referral from other branches.
* So we remove PMOM and masters because we don't want to associate them
* with other branch referrals.
*
* * STEP 5 : Calculate the future number of godson for each referrals.
* It's like the step 2 but we match newcomers with all branches
* * STEP 6 : Give godsons to referrals according to the calculated value in
* It's like the step 3 but we match newcomers with all branches
*
* * STEP 7 : If everyone has now a referral we save everything to DB
*
* Good luck if you want to edit this algo :)
