Streaming features are features which are used for online algorithms.
Reading/parsing of input, and learning through the algorithm are carried out in separate threads. Input is from a CStreamingFile object.
A StreamingFeatures object usually stores only one example at a time, and any function like dot(), add_to_dense_vec() etc. apply with this example as one implicit operand.
Similarly, when we refer to the "feature vector" of a StreamingFeatures object, it refers to the vector of the example currently stored in that object.
It is up to the user to indicate when he is done using the example so that the next one can be fetched and stored in its place.
Example objects are fetched one-by-one through a CInputParser object, and therefore a StreamingFeatures object must implement the following methods in the derived class:
from_non_streaming() to stream features from an existing features object (has to be implemented in subclasses)
The feature vector itself may be returned through a derived class since at the moment the parser is templated for each data type.
Thus, a templated or specialized version of get_vector(SGVector<T>) must be implemented in the derived class.

Takes a set of TParameter instances (base) with a certain version and a set of target parameter infos and recursively maps the base level wise to the current version using CSGObject::migrate(...). The base is replaced. After this call, the base version containing parameters should be of same version/type as the initial target parameter infos. Note for this to work, the migrate methods and all the internal parameter mappings have to match

creates a new TParameter instance, which contains migrated data from the version that is provided. The provided parameter data base is used for migration, this base is a collection of all parameter data of the previous version. Migration is done FROM the data in param_base TO the provided param info Migration is always one version step. Method has to be implemented in subclasses, if no match is found, base method has to be called.
If there is an element in the param_base which equals the target, a copy of the element is returned. This represents the case when nothing has changed and therefore, the migrate method is not overloaded in a subclass

target | parameter info for the resulting TParameter |

This method prepares everything for a one-to-one parameter migration. One to one here means that only ONE element of the parameter base is needed for the migration (the one with the same name as the target). Data is allocated for the target (in the type as provided in the target SGParamInfo), and a corresponding new TParameter instance is written to replacement. The to_migrate pointer points to the single needed TParameter instance needed for migration. If a name change happened, the old name may be specified by old_name. In addition, the m_delete_data flag of to_migrate is set to true. So if you want to migrate data, the only thing to do after this call is converting the data in the m_parameter fields. If unsure how to use - have a look into an example for this. (base_migration_type_conversion.cpp for example)
