There are two methods to read and process a file:
* Use a simple reader event by event
* Use a more advanced algorithm configured with a method of reading the events.
* Use a more advanced processor configured with an algorithm
An example of a simple reader is provided [here](../src/lstdpp128/apps/common/SimpleReader.cpp).
A more advanced strategy is to use a concept of algorithms used through arrays of events.
The advantage is that it is possible to read a block of events, sort them in time and process them.
It can be very interesting for very large files for which the entire sequence of events cannot reside in RAM.
The programmer defines a processor class and can use it by two read strategy (EventArray or EventBlockArray).
An example of such processor and algorithm is provided [here](../src/lstdpp128/apps/common/IterativeVectorInsert.cpp).
