createExclusiveFile: Create a unique filename.

In xega: Extended Evolutionary and Genetic Algorithms

Create a unique filename.

Description

Name conflicts in filenames are avoided by

• Including the time fractions below a second (tfrac).

• Padding the name with 6 random letters.

• Locking and retrying (as a last resort). The program stops after 10 unsuccessful attempts of finding a unique name.
