TemplateData for Extrasolar planet counts

Centralizes the counts of verified extrasolar planets and systems

Template parameters[Edit template data]
Parameter		Description	Type	Status
data field	`1`	Specifies the data value to be inserted Suggested values `Journal` `Book` `Newspaper` `Magazine`	String	required
format code	`2`	Controls the format for as-of data Default DMY Example MDY	String	optional
data source	`source`	Switches the data source as reference Suggested values `NEA` Default EPE	String	optional

The first parameter can be assigned these data values:

asof: The date as of which the data is valid. With asof only, a second parameter can be specified indicating the format of the date to be inserted. {{date}} is used, and the format codes are defined there.
planet_count: The number of extrasolar planets
system_count: The number of systems with extrasolar planets
multiplanetsystem_count: The number of systems with more than one extrasolar planet; The number of systems needs to be calculated by adding (number of planets in n-planet systems)/n for n up to 8.
ref: Adds a reference to The Extrasolar Planet Encyclopaedia Catalog Listing
full: If the entire message displayed on this template is desired
