/**
 * Traverses a TabularData or CompositeData structure to return nested data
 * //from  w w  w . jav  a  2 s  .co  m
 * e.g. To get the the used perm gen memory before last garbage collection
 * value from the result of the lastGcInfo attribute of the
 * java.lang:type=GarbageCollector,name=Copy mbean the path used would be
 * 
 * memoryUsageBeforeGc.[Perm Gen].used
 * 
 * In general the non bracketed values are keys into CompositeData and the
 * bracketed values are indexes into TabularData. For TabularData indexes
 * with more than one value a comma separated list without spaces should be
 * used, spaces are treated as part of the values in the index array.
 * 
 * e.g. [key1,key2]
 * 
 * The brackets aren't mandatory for indexes but are included for clarity.
 * 
 * Curly brackets can be used after a table index to specify a column name.
 * 
 * e.g memoryUsageBeforeGc.[Perm Gen].{value}.used
 * 
 * The column name is only necessary when the table has more than two
 * columns. If the table has two columns then the value is read from the
 * column not used for the index.
 * 
 * @param obj
 *            TabularData, CompositeData, or Map
 * @param path
 *            dot separated string that represents a path through the object
