This function extracts summary data for each transmitter in the file

1	ExtractTagSummary(sInputFile,sLocation)

`sInputFile`	a data frame containing VTrack archive data, this archive is created using the ReadInputData function
`sLocation`	the location at which we wish to extract our tag summary data (i.e. `RECEIVERID` or `STATIONNAME`). The default is `RECEIVERID`

distances are given in meters

`TRANSMITTERID`	a character vector containing the factory assigned transmitter tag id
`FIRSTDETECT`	a vector of class POSIXct of the time of the first location fix
`LASTDETECT`	a vector of class POSIXct of the time of the last location fix
`NODETECTS`	a numeric vector giving the number of transmitter location fixes
`STARTLOC`	a character vector containing the first location at which the transmitter was detected
`ENDLOC`	a character vector containing the last location at which the transmitter was detected
`NOLOCS`	a numeric vector giving the number of unique receivers or stations at which the transmitter was detected
