63  * This class bootstraps the DMF framework, by parsing the configuration file and setting the flow framework.
64  * The configuration file should be could dataManipulationFramework and place under the manta config directory.
65  *
66  * e.g example of a single step in the dmf flow framework.
67  * An empty step form attribute stand for entry point to the flow.
68  * This condition uses the default StringCondition and check if the message is in the way in; If met condition the
69  * plugin will be executed otherwise ignore.
70  * The incoming attribute set automatically by the DMF framework.
71  * <dmf>
72  * <plugins>
73  * <plugin name="transformer" class="org.mr.mt.MantaMessageTransformer"/>
74  * </plugins>
75  * <flow id="">
76  * <step id="s1" from="" to="transformer">
77  * <conditions>
78  * <condition variable="incoming" value="true"/>
