// CLASS HadIoAscii
//
// This class provides methods for easy reading data from ascii files in free format.
// The types of data supported now are: int ('i'), float ('f') and char ('c')
// The format of record in which data have to be stored consists of 
//   keyword - which has to be directly before set of data to be read or
//   keyword:x:n - where additionally x = i,f,c (type) n = number of data to be read
// and after that - set of data for reading.
// Default x = f, n = 1, in case of x = c no need to specify n.
// (see description of public functions below)
