* Construct a target filename according to pattern from a file's name. Filename should be "name.ext",

* <code>${variableName}</code> and are case insensitive. <br>
* There're such variables:
* <ul>
* <li><code>${filename}</code> - full filename of the input file, both name and extension (default)
* <li><code>${nameOnly}</code> - only the name of the input file without extension part
* <li><code>${extension}</code> - the extension of the input file
* <li><code>${nameOnly-1}</code> - only the name of the input file with first extension
* <li><code>${extension-1}</code> - the extensions, without the first one
* <li><code>${targetLocale}</code> - target locale code (of a form "xx_YY")
* <li><code>${targetLanguage}</code> - the target language and country code together (of a form "XX-YY")
* <li><code>${targetLanguageCode}</code> - the target language only ("XX")
* <li><code>${targetCountryCode}</code> - the target country only ("YY")
* <li><code>${1}, ${2}, ...</code> - variables captured by jokers (* or ?)
* </ul>
* <p>
* Most file filters will use default "<code>${filename}</code>, that leads to the name of translated file
* being the same as the name of source file. But for example the Java(TM) Resource Bundles file filter
* will have the pattern equal to "<code>${nameonly}_${targetlanguage}.${extension}</code> ".
* <p>
* E.g. if you have
* <ul>
* <li>a source filename mask "*.ext1.ext2"
* <li>file name "thisisfile.ext1.ext2"
* </ul>
* Then
* <ul>
* <li><code>${nameOnly}</code> will be equal to "thisisfile"
* <li>and <code>${extension}</code> - "ext1.ext2"
* <li><code>${nameOnly-1}</code> will be equal to "thisisfile.ext1"
* <li>and <code>${extension-1}</code> - "ext2"
