Title: Interval Multiplicities of Persistence Modules

Comments: 39 pages. We extended the definition of the multiplicity of an indecomposable module in the persistence module to that of a decomposable module, and slightly changed the definition of essential covering by removing the indecomposable assumption on $R(V_I)$ that appeared in the previous version
