pkCleanData destroys all private arrays of PLASMAKIN. These arrays
are used to hold the chemical data and are created when the data file is read.
pkCleanData( [STAT] )
Why is this subroutine needed?
Although most modern compilers are able to manage the memory efficiently and avoid memory leaks, it's a good programming practice to clean all arrays before leaving a routine or program.
If you wish to build a program that uses more than one input data file (i.e. for batch processing) you must call this routine to clean the internal arrays before reading the next data file.
