monadojs v0.3.2

MonadoJs

This library allow developper to do some common operations on arrays and objects (filtering, mapping, reducing and sorting). The idea came when i've wanted to do sum on nested properties of object, and having to declare intermediate variables and calling popular libraries helper functions to do what i wanted. Also i wanted to have the ability to use the functions from the library with common js functions (like filter, reducer, map...) without the need to always use the pipe functions like in other libraries.
