// Fcl-based tool to give access to build a float array from an array of
// fcl files, each  specifying a FloatArrayTool.
//
// Parameters:
//   LogLevel - Message logging level (0=none, 1=ctor, 2=each call, ...)
//   FileNames - Vector of file name patterns
//   DefaultValue - Value assigned to values that are out of range
