/**
* Task for resolving relative paths and setting absolute path in property value.
*
* This task was created to address a need for resolving absolute paths of files / directories.
* In many cases a relative directory (e.g. "./build") is specified, but it needs to be treated
* as an absolute path since other build files (e.g. in subdirs) should all be using the same
* path -- and not treating it as a relative path to their own directory.
*
* <code>
* <property name="relative_path" value="./dirname"/>
* <resolvepath propertyName="absolute_path" file="${relative_path}"/>
* <echo>Resolved [absolute] path: ${absolute_path}</echo>
* </code>
*
* TODO:
* - Possibly integrate this with PackageAsPath, for handling/resolving dot-path paths.
