Add filters to board responses

[peter-mount]

From UK DepartureBoards:

quick question, would it be much work to add basic filters to the data as url params ie limit to 10 services or do not include terminating service / destination filter (only show services to this destination crs) etc..?

So add url parameters to:

• limit number of services in response
• Exclude terminating services
• Limit entries that only have a specific crs in the calling points

The last one might be tricky as calling points are not generated for cancelled services - might need to use the schedule for that one

Working & shortly on UAT:

• limit number of services returned by adding ?len= to the url with the number to limit it to
• filter out terminating services add ?term=false

Also about to go to UAT is callsAt= which accepts a CRS code and will filter only those services that will/expected to call at a station.

Note: If a service was due to call at that station but has been cancelled then that service will not be included in this filter.

Just a note that this one is finally live - backend for over a week but departureboards.mobi now has it live as of this morning. The only thing left is to filter by station that doesn't use the calling list - I'll create a new issue for that one as that will take tome
