/**
* Allows Options to be created from a single String.
* The pattern contains various single character flags and via
* an optional punctuation character, their expected type.
*
*
*
* Overview of PatternOptionBuilder patterns
* a -a flag
* b@ -b [classname]
* c> -c [filename]
* d+ -d [classname] (creates object via empty constructor)
* e% -e [number] (creates Double/Long instance depending on existing of a '.')
* f/ -f [url]
* g: -g [string]
*
*
*
* For example, the following allows command line flags of '-v -p string-value -f /dir/file'.
* The exclamation mark precede a mandatory option.
*
*
*
* Options options = PatternOptionBuilder.parsePattern("vp:!f/");
*
*
*
* TODO: These need to break out to OptionType and also to be pluggable.
