Get head to head information via API.

[kachelle]

It would be very nice to get head to head information via the API. In that way it is nice to display whether or not a person has already played against another.
And if they already played against eachother, what date it was, and on what tournament/competition.
As is now possible on the competitie.vttl.be site: https://competitie.vttl.be/index.php?menu=4&head=1&player_1=Kjell+Kind&player_2=Tim+Sturm

Input:
homeplayer list & away player list (limit to X amount of players per team).
Or only homeplayer list, then check them all against each other.

{"Credentials": {"Account":"xxx","Password":"xxx"}, "HomePlayers":[ {"UniqueIndex":"500001"}, {"UniqueIndex":"500002"}, {"UniqueIndex":"500003"}, {"UniqueIndex":"500004"} ], "AwayPlayers":[ {"UniqueIndex":"600001"}, {"UniqueIndex":"600002"}, {"UniqueIndex":"600003"}, {"UniqueIndex":"600004"} ], }
And in the reply,
[
{
"HomePlayerUniqueIndex": 500001,
"AwayPlayerUniqueIndex": 600001,
"IndividualMatchCount": 2,
"IndividualMatchResults": [
{
"Date": "2017-09-16",
"MatchUniqueId": 278627,
"HomePlayerRanking": "C2",
"AwayPlayerRanking": "C0",
"HomeSetCount": 2,
"AwaySetCount": 3,
"Scores": "1|4,2|-9,3|-14,4|7,5|-9"
},
{

]
},
{

"IndividualMatchCount": 0
},
{

}
]

Indeed a nice additional feature to have :)

This is not on my personal priorities but if anyone wants to work on this, I'll be happy to help when I can and put it online when ready.

I believe it will require a new API entry. First step is to correctly define the new functions and inputs/ouputs. When this is done, I can probably look at the website code and extract the query that does this.

PR welcome :)
