Improve Automated Documentation

For greater reusability the in-code automated Documentation needs to be improved.

Its presentation on Meta-CPAN is crucial for the successful use.

Current progress of the automated documentation according to Pod::Coverage is:

$ perl -MPod::Coverage=Process::SubProcess -e ''
Process::SubProcess has a Pod::Coverage rating of 0.515151515151515
The following are uncovered: clearErrors, freeResources, getCommand, getErrorCode, getErrorString, getExecutionTime, getNameComplete, getProcessStatus, getReadTimeout, getReportString, getTimeout, isDebug, isProfiling, isRunning, setDebug, setProfiling
$ perl -MPod::Coverage=Process::SubProcess::Group -e ''
Process::SubProcess::Group has a Pod::Coverage rating of 0.129032258064516
The following are uncovered: Check, Kill, Launch, Run, Terminate, Wait, checkiProcess, clearErrors, freeResources, getCheckInterval, getErrorCode, getErrorString, getFinishedCount, getFreeCount, getProcessCount, getReadTimeout, getReportString, getRunningCount, getTimeout, getiProcess, isDebug, isProfiling, isQuiet, setDebug, setProfiling, setQuiet, setTimeout
$ perl -MPod::Coverage=Process::SubProcess::Pool -e ''
Process::SubProcess::Pool has a Pod::Coverage rating of 0
The following are uncovered: add, getFinishedProcess, getFreeProcess, getMaxProcessCount, getMinProcessCount, new, setMaxProcessCount, setMinProcessCount, waitFirst, waitNext

• Process::SubProcess: 51.51%
• Process::SubProcess::Group: 12.90%
• Process::SubProcess::Pool: 0%

On Process::SubProcess rest mostly only the get methods to document which provides already a very good usability.
