Shiny module server for generating match results output

Description

Carries out matching and returns a match result reactive object

Usage

matchResultServer(id, refdata, inputdata, params, sourcecol)

Arguments

`id`	Character ID for specifying namespace, see `shiny::NS`.
`refdata`	Reactive refdata dataset as a `data.table`.
`inputdata`	Reactive `data.table` of the comparison dataset, e.g from `customDatasetServer`.
`params`	Reactive parameters data, e.g. from `matchLinkServer`.
`sourcecol`	Name for the source key column of the joined dataset.

Details

The module initializes a results reactive values list containing NULL values and whenever new inputdata is passed in (clearing previous results). The matching doesn't run until a valid params reactive object is provided, which will call upon the underlying handler matchPair. If successful, the module updates and returns the results reactive values list object with results$params results$intermediate results$pair results$matchtable. Though results$matchtable is rendered in this module's UI with its own download handler, it and the rest are relevant data necessarily forwarded to matchPlotServer.
