Initializing help system before first use

# problem.setLogFile

Purpose
This directs all Optimizer output to a log file.
Topic areas
File IO, Logging, Optimizer
Synopsis
`problem.setLogFile(filename)`
Argument

filename | A string of up to MAXPROBNAMELENGTH characters containing the file name to which all logging output should be written. If set to None, redirection of the output will stop.

Further information
1. It is recommended that a log file be set up for each problem being worked on, since it provides a means for obtaining any errors or warnings output by the Optimizer during the solution process.
2. Alternatively, an output callback can be defined using problem.addMessageCallback, which will be called every time a line of text is output. To discard all output messages the OUTPUTLOG integer control can be set to 0.
