//This is the base class for record separation. For each different type
// of input that requires a special record separation, this class can be
// extended keeping the same interface:
// constructor(file="") --> initialize the object and test input file
// accesibility. When file=="" standard input is
// used
// getRecord():array----> returns an array which contains, as first element
// a logic indicating if everything is OK or not and as second
// element a string containing the next record read from the input,
// in case of success, or a error message. When eof is reached ""
// is returned.
//class RecSeparator {
// function RecSeparator( $file="")
// function getRecord()
//}
//Class for separation of XML simple inputs (one tag marks the record)
