After doing most of the UIMA pear runtime work... I would like to

Currently we work with a customResourceSpecifier. I would like to change
that to a real pearSpecifier.

OK with me.

OK I implemented the following pearSpecifier resource:

<?xml version="1.0" encoding="UTF-8"?>
<pearSpecifier xmlns="http://uima.apache.org/resourceSpecifier";>
   <resourceType>InstalledPear</resourceType>
   <pearPath>/home/test/WhitespaceTokenizer</pearPath>
</pearSpecifier>

The resourceType is the type of the pear archive we use. So maybe in the future we can also work on archived pear files that do not have to be installed before. The pearPath is the path to the installed pear root directory. If we decide to work also on archived pear files, this path can also be a valid pear archive file path.

Additionally the pearSpecifier can have parameters like
 <parameters>
      <parameter name="ParamName" value="ParamValue"/>
  </parameters>
but currently I don't see the need for this.

I also added the necessary methods for the ResourceSpecifierFactory and for the XMLParser.

Additionally to the new pearSpecifier stuff I added an extra step in the pear installation api to automatically create a pearSpecifier when a pear file is installed. So after the installation of a pear file in the main root directory of the installed pear there is a descriptor called <componendID>_pear.xml that can be used to easily run the installed pear file unsing CVD or any other UIMA tooling. With this, no classpath changes or anything else is necessary to run the pear. The created descriptor can also be used to add it to an aggregate that should contain the pear.

With these changes I think the pear stuff is more attractive to use than before.

Any comments or issues on this? If not I will check in the code to SVN.
