+/**
+ * @brief A template class implementing includeMask for filtering data based on field values
+ * 
+ * The IncludeMask class creates boolean masks that identify which elements from a field
+ * satisfy a given condition. It applies an operator to each element of a field and
+ * generates a mask (vector of booleans) where true means the element satisfies the
+ * condition and should be included.
+ * 
+ * @tparam T The data type of the field (real, realx3, realx4)
+ * @tparam Operator The operation class that defines the condition (e.g., greaterThanOp)
+ * 
+ * The class has a specialized implementation for allOp operator which includes all elements.
+ * 
+ * Usage example in postprocessDataDict:
+ * ```
+ * // Create a dictionary with the required configuration for filtering
+ * 
+ * {
+ *     includeMask lessThan;
+ *
+ *     // Diameter of par1 is 0.003, so these settings
+ *     // will select only particles of type par1
+ *     lessThanInfo
+ *     {
+ *         field   diameter;
+ *         value   0.0031;
+ *     }
+ *    
+ * }
+ * 
+ * ```

+/**
+ * @class includeMask
+* @brief Base class for creating inclusion masks for data filtering
+* 
+ * includeMask is an abstract base class for creating masks that filter data
+ * from a fieldsDataBase. Derived classes implement specific filtering criteria
+ * through the getMask() method which returns a Mask object - a wrapper around
+ * a vector of booleans that indicates which elements to include/exclude.
+ * 
+ * This class follows a factory pattern with create() methods that instantiate
+ * the appropriate derived mask type based on dictionary settings.
+ * 
+ * Derived classes can implement various filtering strategies such as:
+ * - Filtering by field values
+ * - Filtering by spatial regions
+ * - Filtering by predefined criteria
+ * 
+ * The Mask objects returned by getMask() can be used in postprocessing operations
+ * to include only the data points that match the specified criteria.
