Description

This patch will contribute a PreConditionComparator implementation that will ignore a specific file type with a particular extension. Users would leverage it by adding e.g., something like the below to precondition-beans.xml, for example to only extract metadata from HDF files:

    <bean id="OnlyExtractHdf" lazy-init="true" class="org.apache.oodt.cas.metadata.preconditions.EndsWithComparator">
        <property name="description" value="Checks the file extension and only extracts met from those files."/>        
        <property name="compareItem">
            <value type="java.lang.String">hdf</value>    
        </property>
        <property name="type" value="equal_to"/>
    </bean>
